Greetings
I'm working on a heavy duty project where I have 2 step motors that are being controlled by arduino; However when I send an arduino signal I send a lot of garbage with it. My baud rates match and if I send my signals through the computer it works perfectly fine. The idea is that when i send a signal it has to repeat this signal so the motors spin, but due to the garbage being send it repeats the garbage, which does is not a valid signal for the motor to spin (valid signals are W, A, S, D, '/' (to stop the motors)). When I check the serial monitor I see that the step motors take one step, then it sends the letter I put in and then it starts repeating the garbage.
Could someone help me please? I was thinking maybe excluding all signals except for W, S, D, A and another one to stop the motors?
Credit for the code goes to someone else, I dont remember where I got it from tho...
