Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: The Only Required Part ! - Photodiode

You Will Only Need A Transparent Photo-diode ,3 mm, 5 mm any of them will work fine !

And Obviously You Will Need an White LED Prefer white one because it's throughput is very good .

its a good idea to build this circuit on a breadboard first , as you may need to tweak distance between LED and Photo-diode .

A Voltage Source Like a 3.7v or 9 v battery

★☆★ Buy Parts from your online local store ★☆★

1) PhotoDiode Transperant http://geni.us/GYAwCMA

2) White Led http://geni.us/4Yrfvbb

3) 3.7v Battery http://geni.us/8V2i1

Step 2: Circuit Diagram (Hint - Series Connection !)

The Circuit is also pretty simple one , its just a series connection of Photo-diode and LED Voltage Source Completes the Circuit !

As a Voltage Source I Used 3.7 v Battery , For Different Colored LED's 9 v battery can be also used

As shown in picture i installed Components onto a breadboard .

Step 3: How It Works !

1. In a Dark Room Photo-diode offers very high resistance and therefore LED Glows Very Dimmly

2. In a Well Lighted Room Photo-diode offers very low resistance and therefore LED Glows Strongly

3. Interesting Thing happens when you perfectly direct Photo-diode towards LED . Led Turns ON

4. But When You put finger between photo diode and led the led switches OFF.

5. Now if you put this circuit in a dark room , LED Stays OFF

6. If You Press Any Button From IR Remote ,LED Turns ON ,This is becouse the photodide capture the infrared light from remote which will decrease the ressistance hence incease the intensity of white LED, and it stays on until you block light between your contraption Pretty Cool HUH !

    It would be interesting if you could setup multiple leds and sensors to create some kind of reaction feedback loop. You could make some interesting light shows.
