Français : Démonstration simpliste de fr:Roue de réaction avec un lecteur de CD portable de type 'Discman' dont le moteur est piloté par un fr:Arduino. Tourner dans un sens pendant 5 secondes, attendre 15 secondes, tourner dans l'autre sens pendant 5 secondes, attendre 15 secondes et recommencer. Le tout est alimenté par un 'powerbank' USB. Le moteur est commandé (en PWM 0 & 255) via un L9110S alimenté en 3.3V.
