This circuit uses no MCU and blinks each of the lights using a capacitor and transistor. I found the original circuit on www.circuitdiagram.com. I used 2N2222 transistors and they are arranged EBC when viewed from the front. I reversed the emitter and collector in the Layout for better positioning and to make the lines neater.

Make it your own

Every circuit here is a live project in Circuit Canvas, not just a picture. Copy this one and change a value, swap a part or move it to a stripboard: the schematic and the breadboard layout are linked, so a part added to one appears in the other.

Or start from a blank canvas and draw your own circuit, with thousands of ready-made parts.
