LED Chaser using 4017 and 555 Timer - PCB

LED Chaser using 4017 Counter and 555 Timer

Introduction A simple LED chaser hobby circuit can be made using 555 timer and CD4017 counter IC. You can use this circuit for decorative purposes. By modifying the circuit in a proper way, you can even use this to control lights working on AC mains. Components Required CD4017 Counter IC - 1 555 Timer IC - 1 LED - 11 680Ω Resistor - 11 10KΩ Resistor - 1 10KΩ Variable Resistor - 1 10μF Capacitor - 1 0.01μF Capacitor - 1 9V [...]

LED Chaser using PIC Microcontroller

LED Chaser is a simple project for beginners that can build using PIC microcontroller. In this 8 LED are running like a Ring Counter. It is very simple and you can create different patterns as you like just by modifying the MikroC program. Here I am using PIC16F877A, one of the most popular PIC microcontroller. This tutorial is on the assumption that, you have basic knowledge in mikroC and Proteus. If you haven't please go to this tutorial. MikroC Code void main() { [...]
