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 from the IR sensor. The IR sensor detects the presence of objects or motion, and its output is read by the Arduino Nano. Depending on the sensor's output, the Arduino Nano sends a PWM (Pulse Width Modulation) signal to the servo motor to perform a specific action, such as rotating to a certain angle.
