- advanced communication between multiple Arduinos using I2C bus.
- most online tutorials covers just one blinking LED with almost no practical use. Slave just executes ONE and SAME function every time Master asks about it. I'd like to outsource slave Arduinos for zillions of tasks.
- simple protocol which enables to send any number of commands to Slave, opposing single return from simple Wire.onRequest();
Strong communication skills are always a key to success:
Say we have one Arduino(Slave) dedicated for position ...
