This circuit is a simple 8 light chaser built around a PIC. This will demonstrate how easy it is to program a PIC and to utilize it in a circuit. It depends in the PIC Programmer.
The following information was extracted from the September 1998 Electronics Now Magazine. The author of the article was Michael A. Covington. In Michael’s article he acknowledges the contribution of David Tait in regards to the “TOPIC” program. This project provides the beginning of a Learning Series on PIC micro controller. I will be providing other projects based on PIC in the future and therefore this project, PIC Programmer, is necessary for any future projects. It will allow you to program a PIC to perform functions that in the past would require numerous IC chips.
Based on PIC16F877 and DS1820
A simple thermometer using DS1820 thermal probes that have a tolerance within 0.5°C.
