Learn how to use light sensor to control LED. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided to help you quickly get started with Arduino.

In this complete tutorial you will learn how to use an LED with Arduino. First, you will setup your circuit with an Arduino board and an LED, and then discover different ways to control the LED. …

It is not hard to use an a LED as a sensor on the Arduino. Just put a LED with the anode (positive = long leg) in analog port 0 and the cathode (negative = short leg) in GND (ground).

Put the LED that you want to use as the sensor with the long lead (this is the anode and positive lead) in pin analog 3 in the Arduino. This could also be an other analog pin, but then you need …
