Good morning everyone,
I'm getting crazy with some issues about the code on my Arduino Uno. I'm a newbie and to me, it looks fine, I don't see any problem, but now I explain everything.
I need to manage a 24V motor through some 5V relays, just to move a platform forward/ backward. I have also 2 micros, one for the "maximum forward position reached" and one for the "maximum backward position reached".
The cycle starts when DI3 is HIGH and to manage the cycle I choose to use the logic by step, using the "switch...case" function.
Basically, when I perform a case, at the end of each one I increase the step.
My problem is that when I force the DI3 making a bridge with the Arduino 5V, nothing happens. Through the monitoring the value of STEP is always 0.
Am I doing something wrong?
Thank you.
