I just want to say that I began my electrical career as a electrical technician by starting out with tinkering with microcontrollers, namely Arduinos. I learned the basics from Drone Bot Workshop and carried the knowledge I learned from it to other fields and through these events impressed my current employer to land a job straight out of community college. Thank you so much for all you do. I will be donating to show my gratitude and appreciation :) I encourage anyone else who understands how valuable and rare it is to find material like the one DBW provides.

I have found the Bob Ross of Electronics. Subscribed.

Bill *ALWAYS* has a way of presenting video's in a very logical way. And he presents a wide range of projects!

Another incredible tutorial video. The level of detail and explanation you provide in these tutorials is amazing. Thanks so much

Great video! Simple and straight forward. I feel I have a better grasp on these than I have ever had.

A video that illustrates in a great way some articles on the Net I had to read when I had to deal with shift registers for my project. I wish you had published this before : clear, informative and now, 74H* are not magic to me anymore! Great examples too!!

Thank you! I've seen multiple videos saying "this is what a shift register does" but never showed how to actually use it

Thank you for the time you give people like myself who are looking to improve their skills with Arduino projects. Your an amazing teacher and I wish you the best in all aspects of life. I love how you explain everything in a normal calm voice unlike others who speak so fast or don't explain in the detail you do. Thanks again

Hi, I have used this Sketch to make my own 8 by 8 LED Matrix with 1 74hc595 and I am also just 14 years old, thank you a Lot!

This is one of the best explanation and tutorials on logic gates I have come across. The examples you’ve created showcase their use very well. Great work and worth the wait! Thank-you! Now I’m off to order some logic chips to play with.

your videos are becoming top notch and quickly my favorite on youtube, keep it coming!

Hey Bill! I needed a good tutorial for my daughter (she's learning digital electronics) and this was my go-to for shift registers. Great video and thank you for presenting this subject in such a way that it is easy to understand for complete beginners!

Thank you Bill! Just what I was looking for. I was lurking around on your forum site and found this in a topic discussion. Your forum website is great! Keep up with the good work.

This video really helped me. Now my 5x5 led display project can be upgraded to have everything on one board. Thank you!

When you talk about SIPO and PISO, you may use branched and directional arrows to illstrate their jobs in a visual manner.

You are amazing! For me, you are the Andrew Huberman of electronics. There is nobody out there that conveys the information needed to create your own schematics more concisely than you.

Another amazing video. Thank you kindly for putting this together, it will simplify a very important and useful process in digital electronics for the amateur/enthusiast.

Great tutorial. I used these for controlling a board of 8 active low opto-isolated relays, in conjunction with a library I made specifically for this setup. Basically, shift registers act like gateways.

Fabulous video and detailed explanation. Not only explaining what shift registers are and their benefits, but also a practical example of how they can be used in the real world (or workshop). Thank you very much.

Very useful tutorial, thank you for the work you put in on this. I did get confused when the clock enable pin was used as the clock and the clock pin was used as the enable. I got the data sheet and sure enough it said those pins are interchangeable. I like the way you taught how the byte was complemented to get it back to what it really represented.

Thanks for all the great support for my hobby! Very good tutorials! Thanks very much for all your work!

Thank you so much for taking the time to do these videos!

Superb!! Your image / write up on your website was even better. Very grateful to you :)

Another great video as usual. I haven't seen or heard anything about DB1 in a very long time. I never expected you to do one a week plus one a week of the component level videos as you had once proposed. That's just to much work! I was however hoping you were going to do a DB1 video every other time. I was not planning on building one right now, but was so intrigued by your concept I needed more. I take it that you were not getting enough interest from other viewers to keep it going? That's really ashame. That looked like it was going to be something really special. I would love to see you bring it back to life.

i just cant get enough of watching your videos , you among a few who i take as my reference to learn a new skill , so thank you very much

Excellent! I needed to read the states of several pir and magnetic switch sensors while also controlling lights. Shift registers fit this problem like a glove.

Very much appreciated! You are making a difference in this world!

Excellent tutorial! Good job man!

Very good explanation.Soothing voice,nice to listen,.Very calm.You got an arduino-fan subscribed!!

You, Sir, have opened the doors to my better understanding of Arduino and bitwise logic, and I thank you sincerely. I'm 62-years-old and discovered the Arduino playground in early January of 2020, and I'm hooked (it's my new hobby). After using the 74HC595 in an early LED display project, I began to study the nuts-and-bolts of the unit, and I find this all fascinating. For those interested in the logic-level workings of the 74HC595 (or any other chips, for that matter), here are a few references that I've discovered along the way that can be used by both beginners and advanced coders alike. For those who aren't familiar with bitwise operations and boolean algebra, don't let the big words fool you; it's as simple as yes or no, on or off, zero or one...just forget about the world of 0s and 9s, and shift into the world of 0x0 through 0xf (hex numbers), and 0b0 through 0b1 (binary numbers (all two of them)). Once I started coding with hex and binary numbers back in 1990, I never looked back. Mentally converting hex numbers into binary numbers and vice versa is simple, once you learn the trick. I've C & Ped a copy of comments I wrote for a 74HC595 bit-shifting LED project I wrote. I'll share the code on the DroneBot Workshop as soon as I can. When I code, I comment a lot; I comment on the comments if need be. // Forward: The 74HC595 is a SIPO (Serial In, Parallel Out) shift register used to store eight bits of serial data, // and to produce eight bits of parallel outputs. There are two data registers inside the 74HC595: // // 1) the SHIFT register, used to store the serial data inputs ([shift: 1] shifted-in by the shift clock, via the data pin) // 2) the STORAGE register, which stores the parallel output data shifted-in from the SHIFT register ([shift: 2] by the latch clock, internal). // // In review: the "shift clock" shifts data into the SHIFT register, and after eight bits are shifted into the // SHIFT register, the "latch clock" shifts the data stored FROM the SHIFT register INTO the STORAGE register, // which produces the eight bits of outputs. (lol I'm not screaming; just making a point.) // // The 74HC595 is mainly utilized to reduce the amount of output pins needed to use from the microcontroller board // (the Arduino UNO board, in this case). Using three pins from the microcontroller board, the 74HC595 provides // eight output pins in a state of either on or off at 5vDC or 0vDC (and no, you can't PWM through the 74HC595). // // The 74HC595 contains 8-sets of master/slave flip-flop logic circuits running on an operating voltage range of 2vDC // to 6vDC (the logic runs at the data-input voltage level), 80μA (maximum draw), and is the coolest little gadget to // entertain one's self with. The more I learn, the more I realize how simple this device really is. When I begin // programming FPGAs (soon), one of my first goals is to create an operational bit shifter. I'm lovin' it! // // There are three states that the parallel output can be set to: ON, OFF, and high impedance. High impedance // blocks any data shifts (and is toggled by the OE (with a bar above the OE) pin). If you want inputs/outputs // turned off? Simply set the OE pin HIGH, otherwise, it defaults to LOW. The shift register can also be directly // overridden and cleared by setting the SRCLR (with a bar above the SRCLR) pin LOW, otherwise, it defaults to HIGH. // // The best reference I've found for the 74HC595 is: lastminuteengineers.com/74hc595-shift-register-arduino-tutorial/ // They do a great job of explaining the internal operations of the 74HC595 shift register in simple terms.

This was great education and demonstration. Thank you!!!!

Super bon boulot! As usual 😉

I'm a complete novice when it comes to basic electronics. I was searching for PISO without knowing it. Thinking it must be named differently because I associated shift registers solely with SIPO functionality. Thanks so much for enlightening me!

I studied a lot. Thank you for teaching me properly.^^ It was very helpful and useful.

Awesome professor! Love it.

You really are a wealth of knowledge.

You do beautiful work.

Very helpful information

Great video! After some initial problems due to my own stupidity (forgot that the same rows on the breadboard are connected ^^..) I got my example to work. Finally I understood how to work with SIPO shift registers and I can't wait to use multiple ones in order to drive more LEDs.

Great videos. Very well structured. Also, being genuine here, serious respect to a guy whose slight speech impediment means he pronounces 'sh' as a kind of 'slzch' having the word workSHop in his title and doing a video on SHift registers. :)

Thank u so much for this clear explaination!

Probably because he's too specific and slow in his way of explaining his projects, this requires a mind-set that accept this type of videos. People these days are stressed and can't put themselves to listen to him for 30-40min about how you get some LED to blink, they just want the fancy product, not the "boring" side of it. I get calm when listen too teachers and or people like this man or Ben Eater (probably butchered him surname...)

Thank you for your excellent presentation. Well done keep it up.

Amazing ! Thank you !

coolest thing ever. great explanation.

love it ..thank you man

Love all your videos and really appreciate your detailed explanations. Just one thing, I would like to request is that you should zoom in the Arduino Code screen so that the words are readable even on smaller devices.

Nice! You can also use 7 segment display to demonstrate the operation of this IC.

Thank you It's very beautiful and practical

Great tutorial!

GOD explanation. trashes those of difficult web explanations by words.

Geee... a great coffee shop video... Aaah, with some Irish-coffee i can watch most anything...:] and this shift is register wonderful stuff... makes me think of the heath-kit days. thaanks a lot...:)

i really like his tutorials

Your videos are really very informative. It would be interesting in adding a part "B" to this video and connect all 8 data pins to the 1602 LCD. This way a hardware contrast can be made from from a software perspective and a hardware perspective between 4 bit mode and 8 bit mode on the LCD?

16:57, I think it's important to keep total current in mind since if you were to wire up two 7 segment displays using 150ohm resistors (mentioned as a possible value earlier), then you would exceed the 200ma limit of the arduino (e.g. 20ma/LED x 16 segments is 320ma).

@@333cgs333 Connect them in parallel, each with their own current limiting resistor. Calculate the current through each LED and total it for all LEDs. Use an external power supply which can provide the correct amound of current (always best to provide more current than required so you won't damage/overheat the supply). Be sure to have a common ground between the arduino and you external supply. You can also search youtube for videos on powering LEDs.

Thank you, Sir!

Very interresting video I didn't think shift register are so useful

You deserve more than you get!

I kept using eight resistors for these shift register projects, so I cheaped out and stuck them in a DIP socket. Works okay.

Very good presentàtion of shift register sipo/piso and Arduino programming . If you can use Ar/Vr/Mr for demo ,it will be excellent .Good job done !!

Hi, I watched this video and said to myself, that's a cool sketch, so I set up the hardware same as yours for the shift register. Then I modified it so that the LEDs would shift from outside to inside and back then repeat. Now, as I was moving the breadboard around while the LEDs were flashing back and forth, the positive 5Vdc from the Arduino connection came out of its pin on the Arduino Uno; and the LEDs still flash as if power is applied to the chip. I have a 150ms delay between LED shifts as follows in the below code segment (this repeats for different binary numbers for the flashing effect): int latchPin=11; int clockPin=9; int dataPin=12; int dt=150; byte LED1s=0b10000001; byte LED2s=0b01000010; byte LED3s=0b00100100; byte LED4s=0b00011000; byte LED5s=0b00100100; byte LED6s=0b01000010; byte LED7s=0b10000001; byte LED8s=0b00000000; . . . void loop() { // put your main code here, to run repeatedly: digitalWrite(latchPin,LOW); shiftOut(dataPin,clockPin,LSBFIRST,LED1s); digitalWrite(latchPin,HIGH); delay(dt); digitalWrite(latchPin,LOW); shiftOut(dataPin,clockPin,LSBFIRST,LED2s); digitalWrite(latchPin,HIGH); . . . From my multimeter, pin 11, the latch pin, varies a bit but averages to about 4.93Vdc and seems to be supplying all the power the chip and LEDs require to keep running. I would love to send you a picture or short video so you could see this and maybe repeat it. Scott in Harwood, MD

Synchronicity: A day before this video came out, I was trying to figure out how I could use, say, n outputs from an Arduino to drive, say, 2^n LEDs. I'm very new to electronics and microcontrollers, but I've been doing software development professionally for several years. I love this circuit because it does exactly what I was trying to solve, the circuits in the IC aren't hard to understand, and it's great I can just buy an IC instead of wiring all that stuff together. In software development we have libraries of pre-defined stuff, just as ICs are packages of functionality. So ICs follow the same principle we do: package and make freely available bunches of commonly used functionality.

Hope systemd or other models of development don't reach this area...

Shift registers are often unknown by hobbyists and forgotten by others. I have seen them in a lot of designs since the 70's. Computers, wending machines and as receiver/decoders in military radar equipment. You find them very cheap on Ebay. Try to get hold of the good old Texas TTL Handbook.There are many fun and interesting chips in the 74 series.Even an ALU.

Muito boa aula, parabéns!

Great video !!

awesome! thanks!!

thank you so much!!!

Very Very useful tutorial .I respect you Sir a lot. thanking you very much.

Do you have a longer intro video with a longer song? I tend to spontaneously bust out into a robotic dance every time your videos start due to the catchy retro 8-bit style tune and it is contagious.
