4:44/4:44 讲座描述 This project introduces us to the HC-SR04 Ultrasonic Sensor. We will be creating an alarm circuit with a buzzer and warning LEDs. You will understand how an ultrasonic sensor works and how to interact with it in code. This is a very handy addition to your electronics...
An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered. In order to avoid modifying the apartment door, the build is housed in a pair of cardboard boxes, taped to the base of the door, with wires passing underneath. It’s a tidy way to handle ...
Buzzer LED Resistor 220ohm Step 1: Procedure The HC-SR04 Ultrasonic Module has 4 pins, Ground, VCC, Trig, and Echo. The Ground and the VCC pins of the module need to be connected to the Ground and the 5 volts pins on the Arduino Board respectively and the trig and echo pins to any...
