### Project 17 Active Buzzer Module ![](media/image-20251203173130599.png) **1.Introduction** This project uses the same codes as Project 1’s, and then the buzzer will ring for one second and stop for one second. **2.Hardware Required** - Arduino Board *1 - V5 Shield*1 - USB Cable*1 - Active Buzzer Module*1 - Dupont Line*3 **3.Circuit Connection** ![](media/wps34.png) **4.Sample Code** ```c int led = 13; // the setup routine runs once when you press reset: void setup() { // initialize the digital pin as an output. pinMode(led, OUTPUT); } // the loop routine runs over and over again forever: void loop() { digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(led, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second } ``` **5.Result** After uploading the codes to REV4 board, you can hear the buzzer ringing and see the L light blinking at the same time with an interval of one second.
