TinkerKit Green LED [10mm]
Overview
The LED is possibly the simplest actuator available. It’s a low power light source available in many colors.
It lights up when powered from an Arduino pin.
Input: Arduino provides a maximum of 40 mA per pin; this is enough to light up the LED throug h the
digitalWrite() and analogWrite() functions.
Module description: this module features a 10mm Green Light Emitting Diode, the standard TinkerKit
3pin connector and a green LED that signals that the module is correctly powered and a tiny yellow LED
that shows the current brightness of the large green LED. A resistor provides the optimal amount of
current when connected to an Arduino.
This module is an ACTUATOR therefore the connector is an INPUT that need to be connected to one of
the OUTPUT connectors on the TinkerKit Shield.
Code Example
/*
based on Blink, Arduino's "Hello World!"
Turns on an LED on for one second, then off for one second, repeatedly.
The Tinkerkit Led Modules (T010110-7) is hooked up on O0
This example code is in the public domain.
