From the project
my first ever PCB!! its a little board with 10 LEDs that chase each other in a loop, and theres a knob on it so you can change how fast they go. thats it. thats the whole thing. but it works and honestly im so proud of it.

built this for Hack Club Half-life and i went in knowing basically nothing about PCB design so if i can do it you definately can.
NE555 runs in astable mode and just oscillates forever, the speed depends on R1, C1 and the pot. that clock feeds the CD4017 (a decade counter) which moves its output over by one every pulse, 0 through 9 then loops back. put an LED on each…
