Step 2 — Tools
1: Wire clippers; 2: Soldering iron
or gun; 3: Hot-glue gun; 4: Knife for
stripping insulation from wire.
Step 3 — Schematic
Solder all parts together on a small
PCB according to the diagram at
left.
By changing the value of R1 you
can change the speed of the LED's
blinking. You can also add a 10kΩ
potentiometer trimmer instead of
R1.
