DIY Ultrasonic Ranging Obstacle Avoidance Car Electronic Kit LED Display Programming Intelligent Car Welding Practice DIY Kit Function introduction: Ultrasonic ranging avoidance, automatically rotate or retreat when encountering obstacles. The digital tube shows the distance of the current obstacle in real time, up to 5 meters. Introduce a new simulation design concept to make the circuit board more like a car chassis, a special motor drive chip, control the forward and reverse of the motor, and flexibly control the forward, backward, in-situ rotation and other movements of the car; the STC single-chip microcomputer control system is more convenient to use. Function setting instructions: 1. Use ultrasonic distance measurement and display the distance on the digital tube, up to 5 meters. 2. Set the obstacle avoidance distance by pressing the button, obstacle avoidance setting range: 0~2.55 meters, the best obstacle avoidance The set range is 0~0.5 meters, the default obstacle avoidance distance is 0~0.2 meters, and 0 means that the obstacle avoidance function is prohibited. 3. Automatically rotate or retreat to avoid obstacles when encountering obstacles. 4. Long press SW1, the digital tube shows the obstacle avoidance distance and flashes. 5. Adjust the distance through the "+" or "-" button, then press SW1 to save and exit.
