Arduino – LED’s, Buzzers, Fans and Outputs

Description:

This project loops through and turns an LED, then a buzzer, then a Fan Motor on and off. This shows students that turning most types of outputs on or off is the same.

Parts:

  • Breadboard
  • LED
  • Piezo Buzzer
  • Micro Fan
  • 220 Resistor
  • Wires

Code

#define led 8 #define buzzer 9 #define fan 10 void setup() { pinMode(led, OUTPUT); pinMode(buzzer, OUTPUT); pinMode(fan, OUTPUT); } void loop() { digitalWrite(led, HIGH); digitalWrite(buzzer,LOW); digitalWrite(fan, LOW); delay(1000); digitalWrite(led, LOW); digitalWrite(buzzer,HIGH); digitalWrite(fan, LOW); delay(1000); digitalWrite(led, LOW); digitalWrite(buzzer,LOW); digitalWrite(fan, HIGH); delay(1000); }
