sends a code like 1001
I think it is ASCII but where can I see it to be sure?
Why does it matter ?
The small buttons go green and red and with ''ALL'' they go orange,
the big buttons have 2 green leds and one red in the middle.
what is so bad with PWM ? I see many people using different methods
Yes I wanted shift register but they bought something else (the sn3218) but I think they bought something else too that has not arrived yet.
It's easier to show you the datasheet of the LED's.
Is there an example for the code?
I have a Power supply with 3-12V and 1A.
I just have to wire one so I can show them how it works and the rest isn't my business
Yes the button part too, what do you mean by splitting RX from TX what do you think is easier?
