Hi there - thanks for reading!
So I have an arduino uno with an adafruit motor shield running two stepper motors and a servo. The steppers are 28BYJ-48 5V DC. The servo is a micro servo.
I am controlling this through a) my hacked TV remote sending hex codes to an IR receiver and b) a processing sketch sending serial information.
My problem still occurs regardless of whether I’m powering the system through either USB or external power.
The problem is that this entire system used to work perfectly. Now it doesn’t. At all. Literally within a single minute it went from working completely to not responding in all cases.
The servo responds by moving to angle 100 when I start up the system - but won’t respond to anything after that. At one point, only the servo would respond - now…nothing.
I haven’t changed anything, I’ve re-uploaded the same code a few times. I’m at a loss. I don’t have good enough income to just buy a new arduino or motor shield, so I’m really hoping I haven’t blown the system.
I’ve attached some pictures and will c + p the code below.
Has this ever happened to you? If so, what was the problem and how did you solve it? Have I blown my equipment somehow?
NOTE: Most of the code used in this project depicts how the system will react to input from either processing or my TV remote, so there’s a lot of repeating information, and a lot of it won’t seem relevant.
