Arduino+PS2 Mouse=Speedometer/Odometer for RC car

Hi all,

I wrote a tutorial in order to be able to measure the speed and the distance your RC car does. Check the tutorial (based on the mouse input from the Playground), here


Thanks dolphin. This is a help.

Love the hack to deal with the speed difference between the mouse and the car's engine. ;D

Simple, cheap and works. Who needs gear ratios?

Thanks for sharing!

Thanks!!! if someone builds one, let me know and send pics!!
