I'm using USB 5V to power my MCU (an Arduino), and I've got a 9V battery pack (6x AA) for my motors. I'm trying to switch that 9V off and on for a motor. I don't need to change directions or control speed, I just need to be able to give it either 0V or 9V.</p><p><a href="http://letsmakerobots.com/node/340">read more</a></p> http://letsmakerobots.com/node/340#comments Electronics transistors motors voltage http://letsmakerobots.com/crss/node/340 Tue, 08 Apr 2008 03:35:08 -0400 TheCowGod 340 at http://letsmakerobots.com
