ScienceProg blog
Here's a new tip for http://www.scienceprog.com submitted by SPman. ScienceProg.com is a blog that has numerous posts on micontrollers and general electronics projects. The latest post on the site is ' Interfacing microcontrollers to external devices ' which is great for those starting with TTL interfacing. Remember, you can't run a motor directly from a microcontroller pin!!
Some other posts including an ultraviolet light source for PCB exposure, ARM7 development board for LPC2148, and an AVR controlled audio-processor
