We also talked about Alex's latest lcd breakout board:
projects ?
motor controller :

- 5V to chip itself; 9V to motor
- alex Hi. suggested transistor inverter to supply both + & - from one arduino
- and use PWM on pin 1, the "on/off" line, to slow down the motor (it's only running part of the time that way)
