How to drive a 7 segment display directly on Raspberry Pi in Python

7 segment displayLast week I bought some 4-digit, 7-segment displays to experiment with. Strangely enough it was something I’d never tried before, so I was interested to see how they work. I googled around looking to see if someone else had done this before. It seems there are several different sorts of 7-segment displays, so you have to find a good match for the one you’ve bought.

You can get them in various guises including: i2c backpack; 12 pins; 16 pins; resistors built-in; common anode; common cathode etc.

The ones I bought are 12 pin, bare, no backpack, no PCB, no resistors, common cathode. Here’s what they look like…

Raspberry Pi Camera Streaming to VLC Player

09/02/2014 Comments off

Recently I discovered the pi’s in my quest for making a device with recognition software to locate items on the ground while being attached to a multi-rotor helicopter.

The Raspberry Pi is perfect. only needing 5v to run means its great for running off batteries etc. anyway to the streaming part.

To stream to VLC from your Raspberry Pi Camera to your computer over a network you need to install VLC Player on both the Raspberry Pi & PC/ Mac what ever.

for the PC/ MAC its simple just go to the VLC downloads page – http://www.videolan.org/ as for the Pi its more complicated.

Utiliser une clé Wifi sur le Raspberry pi

09/02/2014 Comments off

Il existe deux moyens de connecter le Raspberry PI à internet, sois vous utilisez un câble Ethernet, sois une clé Wifi. Avant toutes choses il faut savoir que toutes les clés Wifi ne sont pas compatibles avec le Raspberry PI. Voilà quelque antenne compatible, je vous conseille d’en acheter une de cela si vous n’en posséder pas encore.
