Interactive LED Test 1 - More than just a table!

A while ago I saw some Interactive LED table videos that kinda got me thinking "I should build one of these..." so I did some research and started playing around with IR LED's as sensors. The idea being that the table we use to play cards on could do with some spicing up...

This video shows the first test of a reverse biased IR led used as an IR sensor to power some green LED's. This is the first step to making an interactive LED table using a fairly simple circuit.



(Oh and sorry about the portrait video, I filmed it with my iPhone)

More tests to come...

nice done, Fairlane !
are you using an Arduino ?

Thanks Jimi! Not this one... I'm now using the Arduino but in the video, it's just a quad op-amp that's stepping up the voltage received by the IR sensor to power the green LEDS...

Hello, it looks simple, can you post the schema please ?

This circuit is nice,and I started trying to develop same logic using 2 nested op-amps ..but still not gettin the perfect implementation!! can U help me!!

Hey ASH, I have added another post to help explain the circuit and also uploaded another video... Cheers, Paul
