This is a Christmas tree-themed PCB powered by 555 timer ic and a CD4017 Decade counter.
I made this setup as a soldering challenge kit, We solder all the THT components with a soldering iron and the end result will be a complete Blinky circuit that is themed after a cool-looking Christmas tree.
You could swap the RGB LED with a normal 5mm LED of any color you like. because of the Decade counter, they will all work in a chasing sequence and the rate of chasing can be controlled by adjusting the value of R2 and R3 along with the Value of C1 that is connected to 555 timer ic.
This setup can also be used with a 5V CR2032 coin cell. NOTE: Coin cell and Cell holder will not be shipped.
