BrainBlox: Get your H-Bridge on

Want to enforce total control over that DC motor that has been bad mouthing you for the past week?  Build yourself an H-Bridge (motor controller) and dominate.  With a little time and not too much money you can do just that.  Here is a great tutorial:

Here is an H-Bridge one of us made.  An Arduino is controlling a small DC motor through an H-bridge.  The analog signal (pulse width modulation) being sent to the motor is also output on the LCD screen and is controlled via a potentiometer (variable resistor).  When the potentiometer is rotated the analog signal changes between 0 - 255, is output on the screen and dictates how fast the motor spins.
