Arduino – Bi-directional serial communication with Raspberry Pi

Find the code and diagrams at: https://www.elithecomputerguy.com/2020/12/arduino-bidirectionnel-serial-communication-with-raspberry-pi/

You can send data to a Raspberry Pi from an Arduino, have the Pi calculate the data, and use "intelligence" to send a command to the Arduino. This allows you to fully utilize a Pi as a "compute module" for the Arduino with the ability to access databases, datastores, APIs and everything else a "real" computer can do .

Preconditions:

Analog temperature sensor with Arduino
Raspberry Pi – How to start coding Python on Raspberry Pi
Arduino – Send commands with serial communication
Arduino – Send serial commands from Raspberry Pi
Arduino – Read serial communication with Raspberry Pi
