Multiple sr04 with a single pin
WebHC-SR04 Hardware Overview. The HC-SR04 is an affordable and easy to use distance measuring sensor which has a range from 2cm to 400cm (about an inch to 13 feet). The sensor is composed of two ultrasonic transducers. One is transmitter which outputs ultrasonic sound pulses and the other is receiver which listens for reflected waves. Web13 ian. 2024 · A third HC-SR04 is located the top of the robot, such that it activates a third motor when the user's hand is hovering above the robot. My test code is as follows: #include #define SONAR_NUM 3 // Number of sensors. #define MAX_DISTANCE 20 // Maximum distance (in cm) to ping. NewPing sonar [SONAR_NUM] = { // Sensor object …
