TinkerKit 2/3 Axis Accelerometer module

An **accelerometer **is a device that measures acceleration. It is very common in consumer electronics such as portable electronic devices and video game controllers to detect movement using accelerometers.

Code example:

/*
 Double Analog input, Double analog output, serial output

 Reads from two analog input pins, a T000020 Accelerometer Module connected to I0 and I1, maps the result to a range from 0 to 255
 and uses the result to set the pulsewidth modulation (PWM) on two T010111 LED Modules connected on O0 and O1.
 Also prints the results to the serial monitor.
