Further following up the Arduino set of lectures with topics on Motors, PWM, Trade-offs, and finally an example of directly programming an AVR chip. Part of the Interactive Media Master's program at the University of Limerick.

2 Connections
Continual spin, given current voltage
Reversing current, reverses the direction
Increasing the voltage, spins faster,
decreasing the voltage, slows the spin
High speed but low torque
Gearbox can add torque but at the expense
of speed
