How would I code/connect more LED pins to this setup? Hi.I am having a problem with this project. Arduino; Ultrasonic sensor. So let’s get started. Before, we were using the same function SonarSensor() but calling it only once for our single sensor interfaced with arduino but now we are calling it three times for all the three sensors. on Step 3. //e.g. Code . The sensor module consists of ultrasonic transmitter, receiver and the control circuit. The length of the pulse is proportional to the time it took for the transmitted signal to be detected. Connect HC SR04 as a 3 pin ultrasonic sensor. We will be using the Arduino core, running on the ESP32. LED.
