Jrifedptry 51 MCU Smart Car DIY Electronic Kit Ultrasonic Obsta Avoidance Car Automatic Ranging Robot Programming DIY Kit

2. Ultrasonic distance measurement and obstacle avoidance, automatically rotate or back to avoid obstacles when encountering obstacles 3. The digital tube displays the current obstacle distance in real time, up to 5 meters 4. Introduce a new simulation design concept to make the circuit board more like a car chassis, a dedicated motor drive chip, control the forward and reverse rotation of the motor, and flexibly control the car's forward, backward, in- rotation and other actions; the single-chip control system is closer to the people 1. Using high-quality materials, the quality is guaranteed 5. A wide range of applications, training hands-on ability
