Convert generic camera dolly rail into controllable motorized dolly.

• 5v powerbank input (Portable!)
• Adjustable speed.
• Video mode (Continuous movement)
• TimeLapse mode with camera shutter trigger.
• Can be set Timelapse delay time (time for camera to save image between shot), Motor position (Left or right of the controller) and Time until display is going to dim. Those are available in Settings menu and the configuration will be stored in the EEPROM which means that configuration still remains after power lost.
