The overall controller makes use of a Dorkboard which is a version of the Arduino microcontroller. 2 buttons allow for changing minutes and hours and another 2 accessory buttons are used to disable the movement and to allow for triggering a 'night mode' that quiets the system in the evening. Everything is housed is a very sturdy, custom machined aluminum housing. A 32v DC power supply powers the system.
