Before we can control the speed however, we need to be able to measure it. One of the easiest and most popular ways of measuring the speed is with Optocoupler, and Encoder Wheel. Most of the Smart Car kits...

Instead of using springs for a set of scales I thought permanent magnets might do the trick. Unfortunately I didnt think about the properties of magnets, the magnetic field is not uniform and therefore the scale won't go up in even intervals, instead it seems...
