Im trying to wire thish bridge circuit from http://www.robotroom.com/BipolarHBridge.html. I dont have the diodes because it a low voltage. When i plus the 9v battery into the power bus on the side of the breadboard the arduino powers on. I dont know if its supposed to do that.I want the motor to run off of 9v but controlled by the 5v arduino logic and transistors. What did I do wrong. this is how i wired it
