This Blue LED light module has a shiny white color. It is ideal for Arduino starters. This module can be easy to be plugged on IO/Sensor expansion shield.
NOTE: This LED is wired to light up when the Signal pin is set to low. The reason for this is to prevent the LED from demanding too much current from the microcontroller and damaging the I/O.
If you wish to make this LED light up with a logic high, you can switch the Signal wire (Green) with the GND wire (Black) and the Voltage wire (Red) to the Signal wire's original spot.

Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
