Summary

This circuit involves an Arduino UNO microcontroller, a force-sensitive resistor (FSR), a DC motor driver (L298N), two motors with reducers, and a 3xAA battery pack. The Arduino UNO reads the input from the FSR and controls the motors through the L298N motor driver. The motors are powered by the 3xAA battery pack.
