These instructions refer to old 4 Please upgrade
The Pibrella is nice add-on board for the Raspberry Pi which consists of 3 large LEDs (Red/Amber/Green), 4 buffered outputs (OutE-F) with white LEDs to indicate their state, 4 inputs (InA-D) a built in large switch and a little piezo beeper.
Support for it has been added to the ScratchGPIO V4 developement version.
To use it, 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 BeepXXXX where XXXX is the frequency in kHz that you want the beeper to make (The quality is very low so don’t expect Hi-Fi )
The 4 inputs are recognised as sensor values InA/InB/InC and InD and the switch is called “switch”
To control the brightness of the LEDs or the level of the outputs use redpower/amberpower/greenpower or powere/powerf/powerg or powerh.
Thank you Thank you Thank you Thank you 🙂
Great – but where could I buy a Pibrella?
I’ve just been told its going to be a month or so before they are on the market – sorry 🙁
Latest we’ve heard is Pibrella due mid-late February. At Wishtrac we’ve written a lot of teaching resources for schools using Pibrella – launching at BETT 2014 – see #WishtracPi on Twitter for more info – and Si – the Pibrella support has been fantastic thanks!
No problem – still work to do with getting the piezo to play a recognisable tune 🙂
PS Always available for an personal appearance on your stand on Friday for the price of a 1st class train ticket, 2 nights in the Savoy and a decent pie and eel supper 🙂
