LED Counter in Python on the Pi

Just a quick post to show a video clip of my Raspberry Pi controlling a seven segment LED via the Pi's GPIO port. I plan to extract the code into a reusable library. One possible use will be to display status / error codes whilst controlling other devices. Must stop playing with hardware and get back to the software.

From one LED to seven


Another weekend and another hour spent with my Raspberry Pi. After a rummage about in my junk box I located a seven segment LED. Annoyingly the device was too small to span the gap on my breadboard. About ten minutes later I had fabricated a suitable socket. Once the Pi was fired up I wrote a quick bit of Python to check that I could control all the segments. As you can see from the photograph, this was a success. Next Sunday’s coding session will be to allow me to pass in a number via the command line and have the device display the correct number.
