This module is often used on robots and toy cars to locate obstacles but it can be used to measure distances as well. Distances measured by the HC-SR04 will be shown on our beloved LCD 16x2 display. Take a look at...

It happens to me with my RC Panzer. Sometimes when my kids are about to run it, it moves very slow, low battery. Then they are di...

What really shocked me was the price. I mean-I do realize that such sorts of devices are not really mainstream, but still, it was kinda high. So I decided to m...

I come from a farming background. One of the things we often had to do, was measure the area of a section of land in order to calculate how much fertiliser  was required. This can be done f...

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...
