LED Knight Rider

LED Knight Rider

This Knight Rider circuit is built with CD4017 and 555 Timer IC. There are two modes in this Knight Rider circuit. Works in two different designs when changing these modes. This circuit can be used to decorate houses and decorate a car

LED Knight Rider Working Principle :

The CD4017 IC used in this Knight rider circuit is a decade counter IC. Depending on the pulse given in this IC, the output LED produces a running effect from the first LED to the last LED.

The 555 Timer IC is used to pulse this IC. The 4148 Diode is used to create the Knight Rider Effect in this chaser. This Diode acts like an LED and creates the Rider Effect. It adjusts the 10K pot connected to the Timer IC IC and changes the pulse to 555 so that the LED Running Speed ​​varies.

How To Make :

First I designed the Knight Rider Circuit on the Easy Eda website and created the Gerber file. I uploaded this Gerber file on the JLCPCB website and ordered 10 PCB which costs 2 dollars. PCB was delivered in 8 days. I bought the required components in the Electronic Shop and then I put all the components in the PCB and then soldered using the soldering iron and then cut the Excess Terminal and cleaned the PCB.
