Breakout Boards such as the pi cobbler allow you to use breadboard to build projects They are relatively cheap and great for projects but don’t protect the GPIO pins
One of many add-on boards which offer GPIO protection and extra functionality Developed by the University of Manchester with the education sector in mind 2 relays 8 inputs 0V 5V 8 outputs
7 segment display – using Python £1 each
Sensors don’t have to cost much An 8 input capacitive touch sensor can be bought for £1.99. The same technology as Makey Makey but much cheaper
Using the Data pins These bypass the Piface and go directly to the GPIO pins via a protected circuitThis is needed for speed with some sensors as the Piface is too slow. Low cost sensors/motors e.g.TemperatureHumidity PressureDistance(Ultra sound) Servo/Stepper motors for robotics
Robotics Maplin Robotic Arm £30 each (watch out for offers every so often) Programmable with Scratch & Python thanks to an open sourcemodule called PYusb http://sourceforge.net/projects/pyusb/ http://scratch.mit.edu/projects/17770365/
Use the Python API to write code to control the world. The same script can switch on LED’s or other OUTPUTS. INPUT switches can be used as control
