Test your reaction time against the drag racing lights (Christmas tree lights).

Use the accelerometer to start calibrate it use a 5 second delay and combine with location to have a simulated drag strip! Keep in mind GPS updates at 1hz so this is just for fun not an accurate timing device.

Use as a simple start light when racing RC cars or slot racing (starts with a delay allowing us to set up our controllers).

Includes the option to set a vehicle reaction time allowing a start on 3rd amber instead of reacting to green.

Select one of the following start modes:
- Stoplight - Green light comes on at a random time. Does not use vehicle reaction time.
- Sportsman tree - ambers light up sequentially 0.5 seconds apart followed by the green light
- Pro tree - all ambers light up at the same time followed by the green light after 0.4 seconds
