Xiaoyang's ITP Life

Students in itp are got talented, everyone are creating their amazing products, some make a light sound duck, some sewed leds on gloves, some stick a sensor on a cup…so where is my direction? I find a lego motor in lab, and I’m thinking to make it rotate. It is easy, just supply it with power. Then I want to make it spin in two directions. No matter how I tried to make the circuit, it didnot work. Then I asked Danny, he told me to use H-bridge. So what’s a H-bridge? I find the turial in Tom’s class page and start to test it. Actually, it is not such difficult as it looks like. I made it rotate in different directions.
