Summary

This circuit consists of an Arduino UNO microcontroller, two servo motors, and a PIR sensor. The Arduino UNO serves as the central control unit, providing power and control signals to the servos and receiving input from the PIR sensor. The servos are used for actuation, while the PIR sensor detects motion.
