10 channel led chaser with adjustable speed, Decad Counter Circuit for Electronic Projects, CD4017, 555 timer,
his Circuit is based on LED flashing,If you want to build a 10 LED Chaser circuit we suggest this circuit first. It uses popular IC is a simple and affordable IC-4017 decade counter and IC-555. When we power the circuit, LEDs start glowing one by one for a defined time period. Means first LED Q1 glows and then Q2 glows and Q1 turned OFF and then Q3 glows and Q2 turned OFF and so on. When we change resistance of variable resistor then speed of LED’s increase. Because frequency of 555 timer increases and this increases frequency signal is directly connected to counter’s trigger pin. So that counter changes its state faster ADDITIONAL INFORMATION – 3.
