Arduino Project: Piranha LED Module

Posted by Fiona Su on


This is a special LED module. When you connect it to ARDUINO development board, after program, it can emit beautiful light. Of course, you can also control it using PWM. It will be like fireflies at night. Isn’t cool? We can also combine it with other sensors to do various interesting interactive experiments.
  • Module type: digital
  • Working voltage: 5v
  • Distance between pins: 2.54mm
  • Size: 30*20mm
  • Weight: 3g

Connection Diagram


Sample Code

int led = 3; 
void setup()
  pinMode(led, OUTPUT);     //Set Pin3 as output
void loop()
{      digitalWrite(led, HIGH);   //Turn off led
          digitalWrite(led, LOW);    //Turn on led
