I'm loving your tutorials. I've been coding since the 80s (starting as an IBM systems programmer) but am a total Arduino noob. Your tutorials have been really helpful in getting up to speed. A fun enhancement would be to add a separate calibrate button. When pushed with the joystick centered, it would read the neutral X and Y values, shove them into variables, add a "fudge factor" and then use those rather than hard coding. You know what they say, "Software is never finished; at some point, it's just abandoned." lol

😆 I'm glad we figured out the dead zone during the last Office Hours live chat! It works great!

Nice vídeo and a nice way to introduce Hysteresis in a pratical way.

I know how this is going to sound, but, it is what it is. I love what youre doing. Im a polymath artist/engineer. And as such, I know what its like having projects all over the place that I am working on. I just subscribed, so im not sure full extent of your skills. With that being said, I could only imagine what you would do with a 3D printer and you were able to print your own parts. So, if you were to get 1, Id be able to help you. How? Well, Im a Maya expert and I am capable of printing anything with no limitations with 100% accuracy. So, basically, theres nothing you could think of, that I wouldnt be able to figure out how to print. Im going to be making a series of tutorials that incorporate everything (check my page) from game dev, 3D art, Geometry, 3D printing, engineering etc. Youre already helping me by doing what your doing. So, I figure if there was anything I could do to help you, I would, especially if it meant seeing what you would do with something 3d printed. For example, Im going to start working on a RC Dirt buggie, that transforms into a drone and flys. LOL. And Im going to document it from start to finish. Anytime I get to something that i feel you can explain better, which would be most things when it comes to electric, Im going to direct them to your page. Sorry for the long comment but if you actually check my page youll see im legit. Also, Theres something I havent figured out, maybe it would be a dope video for you to do. I know how to code it in Unreal, but, how would you go about zeroing out numbers to work from a scale of 0-1. For Example, In UE I would code it like this, if defualt value for X is 489, -489 and set X. X now has a value of of zero, then set max to 1000 and divide to give me 0-1. And do the same but for negative in the other direction, so the controls should technically be for accuracy 0 at defualt, -X = -1 and X =1. So .5 would be halfway moving the stick to either side. I can do this in UE but if I could it in the Arduino it would be better for me. I guess I should I mention, the RC Buggie that transforms into a drone, is going to have a VR component so itll be like youre really small driving in VR like a video game, but instead of a video game environment, itll be a real environment.. Thanks, if you took the time to read, and I apologize again for the long comment. Cheers from NYC.

Fun to see that you were able to adjust the negative action from canceling out the antiative reaction?

Thank You for the tutorial videos. Your just too cool!

Wow i was just planning this on my puppet alien animatronic, you ready my mind, dont do that, my wife says its chaotic, 9 projects going at the same time, big huge projects. Love the channel playing in background when in workshop, like Adam Savage your voice is good for concentration.

If you want to control multiple LEDs with a lot of flexibility, and very low software overhead, lp55231 has 3 onboard LED control "engines", for 9 LEDs, which can be programmed with complex sequences, and free-run, with no further MCU overhead, or small I2C instructions that change parameters of the program execution... There is some Arduino support, and TI has a PC-based software development package... There's even a "trigger" input/output pin, to allow "chaining" multiple LP55231's.

It is caused by button bounce, so putting in a delay between the movement of the Y and X about 400 to 600 milliseconds, and a delay at the end of the loop to control the overall loop sequence again 1 second should be adequate.

Great stuff Rachel.

@@RachelDeBarrosLive the topics you're covering are fine. I'm looking forward to seeing the next video about controlling a servo with the joystick.

You should be able to simplify the code and make it work more consistently by writing it like this. if (buttonState == Low){ digitalWrite(upLed, HIGH); digitalWrite(downLed, HIGH); digitalWrite(leftLed, HIGH); digitalWrite(rightLed, HIGH); }else{ analogWrite(upLed,upBrightness); analogWrite(downLed,downBrightness); analogWrite(leftLed,leftBrightness); analogWrite(rightLed,rightBrightness); } The dead-bands in the map statements should be sufficient to set the values to zero near center.

great video i have some idea to finaly use my joystick for a projet (gonna use it with yx5300 mp3 player, up/down to change folder, and left/right for playing previous/next song, and button trigger for payse/play) thx

That's a great project idea!

Will it be possible for you to make a video on PH calibration on Arduino with detail. It will help me on my project.

How about setting all brightness variables to 0 at the beginning of each loop, then read the pins using min() and max() functions, and map the values to the respective brightness. Finally write to all leds. This would eliminate all IF statements.

Hi Jim! Arduino is indeed based on C/C++

So analog pins are acting like some kind of potentiometers and Digital like on and off switchs am i wrong?

@RachelDeBarrosLive

Ай бұрын

You're right! The X and Y axes on the joystick each have a potentiometer. You can see them if you pop off the knob. The button works like an on/off switch.

There is a logical error in the code. When checking for x and y values being in the "zero zone", those should be checked independently. Otherwise one could have a situation with x being in the "zero zone" while y is not (or y but not x), causing the lights to stay on.
