Changed from dev mode to working mode. Lamp turns on after 24 frames. Will make it configurable.

Code is in test mode for getting approximations of the motor speed with no load, under single strand of film load and with 2 films. Should be possible to create a control loop to maintain a roughly-accurate speed.

Add proof of concept blink script for wiring the lamp to be driven by +5V and the TIP120 controlling 3 LEDs at once.

Motor speed is now calculated (flawed). Tests can be run on various PWM speeds, resolutions and with and without loads to determine the ability for the printer run at maximum speeds.

Update README to better reflect current state of the project and add Acknowledgements section.

Make some sacrifices in the DriveMotor class to make it non-generalizable. Working towards porting timing functions from encoder proof of concept sketch.

Motor behavior is stable. Discarded one of the L298N boards: now we can run the drive motor off one channel and both takeup motors off another. DO NOT USE LESS THAN 2A. Using 1.3A the motor controller board draws too much and shuts it down. Removed the rerences to Picture/Stock and am just using takeup. All progress at Worm.

Test second set of pins

Fixed the pinouts for the drive motor. Temporarily disabled takeup.

Add Serial output for debugging

Resizes reels. Was 99mm diameter and works in larger patersons but not the standard 2 reel model. Resized to 94mm to match the standard reels. Removed a single rotation of the spiral. Should fix the spiral implementations to accept a desired length, not just an integer of rotations.

Create the Lamp class which will abstract to different lamp types before one is settled on.
