It is common opinion that “blink LED” project is the most difficult and the most useful example in microcontroller programming. That is understandable because you must spend a lot of time to learn installation process and usage of IDE (Integrated Development Environment), to learn architecture of specific microcontroller and so on. We will explain in this article how to make new project in MPLAB IDE for dsPIC30f4013 and how to blink LED as simplest project with MCU.
Microchip dsPIC30f4013 microcontroller and Telit GM862 GSM modem – hardware implementation

Since this hardware will be used in many projects, we give you detailed description of schematics and PCB board realization.
We used Microchip dsPIC30f4013 because it is very powerful MCU with plenty of peripheral possibilities. If you need a lot of processing, such as fast ADC, this is right choice for you. Also, this MCU isn’t expensive, about 5 EUROs.
Object surface Color detection using AVR ATmega8 and ADJD E622 QR999 light to voltage converting sensor.

Accelerometers and gyroscopes are used for various safety features in modern vehicles. In this article we used Parallax LISY300 Gyroscope Module to measure Gyroscope PCB rotation speed and current position. The complete project is available for download at the bottom of the page. Results turned out to be better than we expected. An error is only few degrees in 10 full circles turn. You can read more about this sensor in this Featured components - LISY300 Gyroscope Module article.
