StarLight

Blinky Board

LED chase ("blinky") circuit created for beginners in Stasis.

Components

NE555 timer as a pulse generator CD4017 decade counter to control outputs Several LEDs as indicators

Pulses generated by the 555 timer trigger the 4017, which switches LEDs to form a running light.

Advantages

Speed control using potentiometer Easy and newbie-friendly design Use of popular parts Perfect for digital & analog electronics basics education

How it works

1. The NE555 chip functions in astable configuration to produce clock pulses.
2. Clock pulses are fed into the CD4017 counter.
3. The counter shifts from one output to another.
4. Outputs activate LEDs to produce the chaser effect.

Quick start guide

1. Load the project in KiCad
2. Examine the circuit and board diagrams
3. Generate Gerbers (or download ZIP file)
4. Order PCB or assemble on protoboard
5. Install components from bom.csv
