Instructables
First of all, I'm from Switzerland so please excuse my english mistakes.


Here is one of my first little project I did with my Arduino Uno.

It's is just a little light seeker. The servo turns towards the light.

I made a video to show you what it does :

Step 1: The wiring

Picture of The wiring
Here is the exact wiring I used.

The only difference is that I fixed the photoresistors on the servo (but I couldn't do it with the program)

Also I used a 9V battery in the video, it was plugged in Vin and GND.

The resistors are 200 Ohm for the LED's and 10 KOhm for the photoresistors.


Hi, I like your project because your project is cool but simple at the same time! It would be fun to work on this project! Could you give me your contact details so that I could ask more question on it?
I would like to know what kind of photoresistors did you use and how did you hook up the photoresistor to the servo so that it'll spin acccording to the light detected by the it.
