Summary of the Circuit

This circuit consists of an Arduino Nano microcontroller, an infrared (IR) sensor, and a servo motor. The Arduino Nano serves as the central processing unit, controlling the servo motor based on the input received from the IR sensor. The IR sensor detects the presence of objects within its range and sends a signal to the Arduino Nano, which then processes this information and actuates the servo motor accordingly. The servo motor is used to perform mechanical movements in response to the processed signals.
