ScratchDuino is a highly customizable, simple and interactive open source robots construction kit based on Arduino. Unique features of ScratchDuino are simplicity of assembly by using magnetic-mount parts and simplicity of programming the AI by MIT Scratch, a visual program language. Scratchduino can be used as an interactive educational open source platform for kids and beginners, as well as a vast experimental kit for advanced robots enthusiasts. [ LinK ]

Almost every robot needs to power a motor of some sort or another. Problem is that motors take quite a lot of power, compared to what most microcontrollers operate with. To solve this problem, robots use what is called a motor controller, which usually amounts to some form of electronic switch that can turn on a very high voltage, using a very low one. That’s what we’ll be making today! [ ]
