Arduino Multiplexing with Transistors

[@mrnogueira985]

Really like your youtube content. would be nice if you have a playlist with arduino tutorials

[@iAyanPahwa]

Great informative video as always :D Would love to see more :-)

[@ziar6800]

Thanks really informative and helpful

I think you did really well here, thank you for this. If I may, I have only one suggestion, the only thing I think that needs clarification is the polarity of the transistor that you were using, you did super impose an "N" on the transistors but this might leave a few questions for some lesser informed viewers as to what this may have meant, or they would go out and get a PNP an find that it would not work when connecting according to your connections as shown, So maybe just a clarification of NPN vs PNP, might give just that little bit more info to someone not as clued up on electronics. Other than that I would say a brilliant delivery, and very well done!

Hey! Thank you for the clarification!

Thank you. Really helpful.

How you program node mcu to differentiate x,y axis inputs cuz it seeing just values and what is the latency of the setup ?

[@engineerish]

How to differentiate between the X and Y signals of the joystick is what the video is about so I'm not sure I understand your question. Don't know about the latency - should work for most use cases I believe (although in the example code I've added a delay of 500ms you probably want to remove)

@@engineerish sorry I didn't watch it carefully I do see that you use print with x and y axis initially (misunderstood that just raw data from x,y axis is fed) and you used delay of 0.5s that quite high should be close to 0.01s-0.1s that would be better . Thank you.

I also feel stupid to ask this question after watching carefully 😂 . By the way there will be reading delay after reading x and then going to read y , unless tested on a game/ response counter I can't trust the accuracy for correct reading of y axis , imagine you moved to one position then to next meantime the x postition is sent but y axis position is read in different location cuz you were moving it to different position . I don't know if it really read accurate.

@@engineerish thanks for replying that was very thoughtful done video .
