Eli the Computer Guy's video: Arduino - Bidirectional Serial Communication with Raspberry Pi

NOTE!!! LINE 18 SHOULD BE: ser.write(b"all\n") Find Code and Diagrams at: https://www.elithecomputerguy.com/2020/12/arduino-bidirectional-serial-communication-with-raspberry-pi/ You can send data to a Raspberry Pi from an Arduino, have the Pi compute the data and use “intelligence” to send the Arduino a command. This allows you to fully use a Pi as a “Compute Module” for the Arduino with the ability to access databases, data-stores, API’s and anything else a “real” computer can do.
