Summary

This circuit integrates an Arduino Nano microcontroller with an HC-SR04 Ultrasonic Sensor and a Vibration Motor, powered by two 18650 Li-ion batteries. The Arduino Nano serves as the central processing unit, controlling the ultrasonic sensor to measure distances and activating the vibration motor based on the sensor's readings. The batteries provide the necessary power to the system.
