Summary of the Circuit

This circuit integrates an Arduino Nano microcontroller with an HC-SR04 Ultrasonic Sensor, an ATTiny microcontroller, a potentiometer, and a resistor. The Arduino Nano serves as the primary control unit, while the ATTiny is used for additional processing or control tasks. The HC-SR04 sensor is used for distance measurement, and the potentiometer provides an adjustable voltage input. The resistor is used to form a voltage divider or to limit current in the circuit.
