so a while ago i did a post about the ir detector by this guy commando well this time he has given me permission to do another post for beginners this is a project about light sensing leds.

 i know in the past we only did projects on how to produce light with a led but this guy actually did the opposite and is able to produce electrical signal from light which i thought was cool. as well there is no soldering all you need is two led OH YA and a thing called an arduino.

an arduino is a programmable micro controller which we will be using a lot in future projects so if you don't already have one get one from your local electronics supplier anyway here it is:
