Color-changing LED glowies

This is pretty sweet project for beginners in PIC microcontrollers. It is a device that glows red when heated and blue when cooled.

Microcontroller used in this project is PIC12F675 with built-in A/D converters. Two identical silicon diodes are connected to two analog inputs, that will change it's forward voltage drop when ambient temperature changes. One of diodes is used as a reference and the other to detect a change in temperature. Device is powered from a 3.6V Ni-Cd battery which is constantly re-charged from a solar panel. Source code is written in PIC Basic and is available for download on project page.

Super !!! Baš mi je nešto ovakvo trebalo za učenje rada sa mikrokontrolerima :)
