I recently found a power inverter thingy (or what ever you call) works to power my Arduino off the AC from my house. The problem came when tried to run a DC motor off the 5V power supply. As soon as I connect the motor, the power regulator (I quite sure thats what it is) starts to heat up real fast. It works perfectly when its powereed by USB but as sson as I plug it into the wall it starts heating up. Does anyone know What the problem is?
MAybe its just normal, I mean its not like its smoking or anything... it just gets really hot.
