LED chaser using 555 timer + 4017 IC on breadboard by Automation BD

A tutorial on how to make an LED chaser circuit / sequential LED flasher using 555 timer IC and CD4017 IC on a breadboard. Short Explanation of this circuit: ------------------------------------------------------- We have used 555 Timer to work in Astable Mode. That means the output changes between high and low (PIN 3). The speed is dependent on the R1, RV1 And C1. Then the Output is send to PIN 14 of 4017 IC. And 4017 IC is a decade counter and has 10 outputs so whenever it feels a high to low transaction at it's clock input which is pin 14. It changes it's output from 0 to 10 and that looks like LED's are chasing each other. Components Required: ------------------------------- 555 Timer IC CD 4017 IC LED Lights x10 Resistors: 100VR, 10K and 220 Capacitor: 10uF Breadboard Lot of Breadboard Connectors Power Supply: (5-9)V ----------------------------------------------------------------------------------------------------- Subscribe Automation BD: https://bit.ly/2DyLaeE ----------------------------------------------------------------------------------------------------- Connect with us......................................
