Bill of Materials
This open source hardware project contains no parts.
Steps
6. Insert 2k resistor
Next, insert two 1k resistors in series between the positive lead of the capacitor and pin 7 of the 555 timer. Since these two resistors are in series, their resistances add and they are equal to one 2k resistor. Alternately, you can insert a single 2k resistor instead.
7. Insert 1k resistor
Install the final 1k resistor between pin 7 of the 555 timer and the +9V rail.
8. Plug in 9V battery
Plug in the 9V battery, connect the black wire to the ground rail and the red wire to the +9V rail. Enjoy your blinking light!
