Project is going quite well - I recently had 6 Arduino's in a class with age 10 pupils controlling stepper motor,servos, 7 seqment display, LEDs and a PIR Sensor.
They made a musical box twirlling ballerine with the stepper motor, stop/go flag with the servo, dice with the LEDs and 7 Segment display and a burglar alarm with the PIR Sensor 
- Be able to control digitial outs (Done)
- Accept Analog input (Removed at moment - too much data aat moment swamping serial comms)
- Control PWM outs (Done)
- Make an install.bat file for PC so it installs Python 2.7 together with pyserial, pyfirmata and my handler prog to make it easy to deploy for Scratchers (Got one that works on Windows)
- Auto-find the Arduino port so it doesn't have to be manually configured (Done on Windows)
- Controls two 5 wire unipolar steppers (Done)
- Servo control (Done)
