12 Channel LED Chaser with PIC16F84A

Today we have a new category “Projects” and a new electronic  project 12 Channel LED Chaser with PIC16F84A.

This project is based on the popular PIC16f84A micro-controller.The heart of this project LED chaser is the PIC16F84A PIC microcontroller.A 4MHz crystal and capacitors C1 and C2 22pf is used for providing clock pulses to the micro-controller. The input voltage can be anywhere from 9 to 12 volts but the PIC microcontroller requires a precisely 5 volt supply.This 5V is provided from 5 volt regulator 78M05. Diode D1 1N4001 protects the circuit from accidental reverse polarity of the input voltage.

Please note that the 16F84  without the ‘A’ suffix  are not suitable for this project.  You must use the 16F84A  parts.

For this project I made a  PCB using toner transfer method. More photos on Facebook Fan Page.

    hi! I look for chaser kit: inpunt 12 volts; outpunt 12 volts/10-25w per channel aprox; 4 to 12 channel. Do you know something, please send me information to jorge_siness@hotmail.com. Thank you

    I was about to make one when I found this http://www.ledmagician.com
    saved me quite a bit of effort. Thanks for sharing this project though! You have lots of cool stuff here!
