Hello! I am working on a project and ideally I would like to start and stop the loop of an Arduino with a Raspberru PI. The idea is to send a signal from the Raspberry PI GPIO pins to the Arduino pins and trigger and ISR as follows: volatile bool start = false; void start(){ start = true; } voi…

Signal from Raspberry PI to arduino

My project uses USB to communicate between the two

Arduino can be powered bu both DC-input (and on pins..?) and the USB. Will it run on the USB power from the RPI

Yes.
