Summary of the Circuit

This circuit consists of two microcontroller boards: an ESP32 Wroom Dev Kit and an Arduino UNO. These boards are interconnected through serial communication, allowing them to exchange data. The ESP32 Wroom Dev Kit is a powerful microcontroller with Wi-Fi capabilities, while the Arduino UNO is a widely-used microcontroller board based on the ATmega328P. The ground pins of both microcontrollers are connected to establish a common reference point for the voltages.
