RS485 Serial Communication between Arduino Uno and Arduino Nano
circuitdigest.com
RS485 Serial Communication between Arduino Uno and Arduino Nano
In this tutorial, we will learn about RS-485 Serial communication between two Arduinos and then demonstrate it by controlling the brightness of the LED connected to a Slave Arduino from Master Arduino by sending ADC values through RS-485 Module. A 10k potentiometer is used to vary the ADC values at Master Arduino.
