To use it, launch ScratchGPIO5 Plus and create a variable called AddOn and set its value to Pibrella in your On Green Flag event.
You can then use the usual AllOn/Off broadcasts and well as individual broadcasts for Red/Amber/Green/OutputE/OutputF/OutputG and OutputH
Also there is a special broadcast BeepXX where XX is the equivalent Scratch note value (60 being Middle C) The sound quality from a piezo is not the same as a large speaker so expect to be able to compose a top ten hit :)
BeepXX,YY is also available where YY is note duration
The 4 inputs are recognised as sensor values InputA to D. These give “off” normally and “on” when activated. The switch is called “switch” and gives off and on.
== Les sorties ===

To control the brightness of the LEDs use PowerRed/PowerAmber/PowerGreen
To control the power settings of the outputs, use PowerOutE to H.
You can connect up a low-cost 5pin stepper and connect it to the outputs (Red to any left hand one, the other 4 to the 4 right hand ones) and use a variable called Stepper to make it turn.
Note new addition – MotorE..H variable
TOPTIP – set a variable called Bright from 1 to 100 and your can control the brightness of the VERY bright LEDs
