Everywhere it's specified that A.Due has same pin layout with Arduino Mega, so you can use Mega's Sensor Shield on Due.

On this sample I would like to explain why PID-control should be used for speed controls and how the direction can be inverted.

This project uses an ultrasonic distance sensor to create a pocket of wave interference where a small object can be levitated.

Use a normal LED to sense light.

This project allows you to draw your own controller to be used with anything. It utilizes capacitive sensing and graphite's conductivity.
At first, thanks for your comments.
"...in the bridge circuit the bottom 2 transistor should be NPN not PNP as the current is in reverse..."
It's not a must actually... Perhaps you considered another path for reversing current. My considerations was either T1A-Motor-T1B or T2A-Motor-T2B paths.
"...putting 4 diodes between collector and emitters will protect the transistors from spikes back EMF from the motor induction..."
I think if transistors are selected at suitable ratings, effect of spikes would be negligible during normal operation. Anyway such spikes by induced coils of DC Motors, appear mainly when motor is stopped. But it's a transient case and takes very short while that can be handled by transistors.
Thanks for interesting, and hopefully all of them will fit well on your implementations.
