We want to send existing code instructions from Raspberry to two arduino mega. The instructions must be able to be sent from Raspberry to each arduino simultaneously. The the arduinos send the signals to the controllers which move the stepper motors. Each arduino is connected to eight stepper motors and they must be able to move simultaneously.
Hi. I'm professional programmer/electronic hardware developer with experience over 20 years. I have experience with connection 2 arduino and PC or PI. We can discuss project in chat. Regards, Alex.
