A while back I made a blog post about a PIC10F200 Project: The Annoy. In this project they combined the simplicity in design along with the creativeness that I always look for, into a project with no real use other than for fun. However, the project seemed a little too large and we felt we could …

LCDs are often used in microcontroller projects. Most used are these green character displays with two or more rows to display menus, status or debug messages. With mass production of mobile phones, color LCDs get that cheap, that they can be used as replacement. Some time ago I ordered a Nokia 6100 LCD including breakout board from …
Connecting Bluetooth Module with Development Board The Bluetooth module has seven interface pins of which two are NC (not connected) pins. The table below shows how you can interface with it our low cost AVR development board. Bluetooth Module Dev Board GND GND RST PD2 TX PD0 RX PD1 NC NC +5V IN VCC Connecting Output Indicator LEDs …

Who wants to go outside to see if the mail has arrived? In the cold winter or rain I’d rather not have to put on a jacket and shoes, only to find that there was no mail. This project will notify you of the mail carrier’s visit, and as a secondary function it will remind …
