- Slide 1
- Presentation by John Lamb Trainee Master Teacher Monkwearmouth Academy Physical Computing with the Raspberry Pi
- Slide 2
- HDMI Composite video Ethernet USB Audio Power GPIO Raspberry Pi Hardware
- Slide 3
- Breakout Boards such as the pi cobbler allow you to use breadboard to build projects They are relatively cheap and great for projects but dont protect the GPIO pins
- Slide 4
- 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 8 inputs 8 outputs 2 relays 0V 5V
- Slide 5
- Making the Piface classroom friendly
- Slide 6
- The final unit safe to work on
- Slide 7
- Classroom Friendly Unit
- Slide 8
- Traffic lights using scratch
- Slide 9
- 7 segment display using Python 1 each
- Slide 10
- Interest and enthusiasm
- Slide 11
- Sensors dont 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
- Slide 12
- Using the Data pins These bypass the Piface and go directly to the GPIO pins via a protected circuit This is needed for speed with some sensors as the Piface is too slow. Low cost sensors/motors e.g. Temperature Humidity Pressure Distance(Ultra sound) Servo/Stepper motors for robotics
- Slide 13
- Maplin Robotic Arm 30 each (watch out for offers every so often) Programmable with Scratch & Python thanks to an open source module called PYusb http://sourceforge.net/projects/pyusb/ Robotics http://scratch.mit.edu/projects/17770365/
- Slide 14
- Use the Python API to write code to control the world. The same script can switch on LEDs or other OUTPUTS. INPUT switches can be used as control
