71. UART-Based LEDs Control

Build a system where two microcontrollers communicate via UART (Serial Communication) to achieve the following functionalities-

Functionalities

1. A potentiometer connected to the microcontroller1 controls the brightness of an LED2 connected to the microcontroller2.
2. A push button switch connected to the microcontroller2 toggles the ON/OFF status of an LED1 connected to the microcontroller1.
3. Serial terminal(e.g., Putty, Arduino IDE) output
   • Microcontroller2 prints the received ADC values.
   • Microcontroller1 prints the LED1 status [ON or OFF].
