DIY Ultrasonic Ranging Obstacle Avoidance Car Electronic Kit LED Display Programming Car Welding Practice DIY Kit

DIY Ultrasonic Ranging Obstacle Avoidance Car Electronic Kit LED Display Programming Car Welding Practice DIY Kit Ultrasonic distance measurement and obstacle avoidance, automatically rotate or retreat to avoid obstacles. The digital tube displays the current obstacle distance in real time, up to 5 meters. The introduction of a new simulation design concept makes the circuit board more like a car chassis, and the dedicated motor driver chip controls the motor forward and reverse rotation, and flexibly controls the car's forward, backward, and in- rotation. The single-chip control system is more convenient to use.
