Exercise 1

Look at Arduino "AnalogInOutSerial" example. Modify it to work with libmaple. Extend it so that it take commands from serial port. In particular, brigtness of LED should be set by a command and voltage should be reported only when asked by a command.

Exercise 2

Try libmaple example controlling servo. Modify program to take commands from serial port.

Exercise 3

Write a program using libmaple to control stepper motors. Modify it to take command from serial port.
