Integrated Circuits (w/ Shift Register demo!)
Today, we learn about IC chips, and put one on a breadboard with an Arduino to test it out!
Last time when we looked at Logic Components, we understood how components like logic gates, latches and flip flops worked. However, those are pretty abstract, and don't tell us much about what actually gets placed on a circuit board.
Today, we have with us a 74HC595N Shift Register, and we use it to try and understand the fundamentals of integrated circuits!

Hello and thank you very much for your comment! Very happy to be of help =)
Wow ...I was hoping to learn how a shift register worked and only had to watch your incredibly well presented tutorial just once so now I got it. Really good, thank you.

Hey, Can you help me on my assignment , I have to make a 3000w 48v power supply but i can't find any regulator which can withstand that much current.

What is the program he uses to simulate the logic of the IC chip around 5:40? Thanks.

I don't actually know C (I still need to learn it), but I'll see if I can explain it in pseudocode. Loop Shift_Register_Output Data_Pin, Store_Clock, Shift_Clock, 0xCC Wait 240ms Shift_Register_Output Data_Pin, Store_Clock, Shift_Clock, 0x33 Wait 240ms End Loop Function Shift_Register_Output Data_Pin, Store_Clock, Shift_Clock, Data For I=7 to 0 T=Bitshift_Right(Data,I) T=T AND 1 Pinout Data_Pin, T Wait 10ms Pulse Shift_Clock End For Pulse Store_Clock End Function Function Pulse Pin Pinout Pin, 1 Wait 10ms Pinout Pin, 0 Wait 10ms End Function

Oh wow, did you just derive code for shifting out a byte to the register? Pretty impressive job =) I'm fairly certain that this will work correctly, though I could probably nitpick on a few really minor things =P 1) Note your waits: "ms" is millisecond, and we usually represent microseconds with the unit "us" (since it's a bit hard to type "µs"). Waiting between pulses is measured in microseconds, not milliseconds. No harm in waiting for a longer time, of course, but that means less work done per unit time. 2) You bitmask in a very interesting way. What I see more often are people shifting a mask, and then applying that mask to the input data, but you seem to be shifting the data instead. Again, no problem with that, just makes it a tad harder to read, especially with the loop going backwards =P Pseudocode for that part using this method: for i from 0 to 7: mask = 1
