Summary

The circuit in question is designed around an Arduino UNO microcontroller, which serves as the central processing unit. The circuit includes two servo motors and a rain sensor. The Arduino UNO provides power to the servos and the rain sensor, and it also controls the servos via PWM signals. Additionally, the Arduino monitors the digital output (DO) of the rain sensor to detect the presence of rain.
