Today’s project is a little write-up that shows you how to connect up a relay with some circuitry to a parallel port. This will then allow you to control any household appliance through software on your PC. The project write-up has the software, circuit diagram and explains how it all works.

This project uses a sharp IR sensor and some data processing. Then the data is visualized through a program. Visualization of data creates a way for us (humans) to understand data quicker, compared to when it is in raw number format.

Today while I was looking around the inter-webs, I ran across this psuedo-ARM project index. The index is mostly an assortment of example programs for the more advanced features like timers & interrupts. Definitely worth a look if you need more ARM example code to look at.
