Drag Tree 2

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
