@tscinbunyrobot: Programming an obstacle avoidance car Do you know how it is implemented? The ultrasonic sensor measures the distance to the obstacle by transmitting and receiving sound waves. After being combined with the servo, when the obstacle distance is detected to be less than the safety threshold, the car stops, and the control system adjusts the direction through the servo, detects whether there are obstacles in the surrounding direction, and then controls the car to turn to avoid obstacles.#programming #DIY #arduino
