I have built a machine that goes through a process using 2 stepper motors, some servos, a series of micro switches, and o would like to add optical switches for position feed back, I am not a programmer and finished reading about Ardublock coding, similar to scratch, can you point me in a direction for a arduino or pi board with inputs outputs to drive the mentioned components and will also let me program its features using these block coding programs, I have seen the keyestudio set of sensors, so something like that.
Your help is appreciated.
Thanks
