Arduino WiShield + MAX7219 7 Segment Display
For this project, I wanted to build a device capable of displaying up to 8 digits on a seven segment display. Sounds easy, right? The catch is, I wanted to retrieve these digits from the Internet over WiFi.
I took this opportunity to try out the ever-popular Arduino platform. Arduino turned out to be a good choice for this project for several because it has:
- an easy to use, Arduino compatible WiFi adapter (WiShield) put out by asynclabs
- a library available for talking to the WiShield with examples included
- a MAX7219 interface library
- an onboard USB programmer and a software programmer that works on Ubuntu
