Hello friends!

Parts list above to make your very own timer circuit! Play around with various capacitors and resistors to see how they affect the output on the LED. Some links below to optional equipment:

  • This >multimeter (123-3366) is great to start with. If you're getting super serious about electronics and want to invest in more equipment, I can't recommend my Fluke 177 (025-2793) enough!
  • For this project, a PC-based PicoScope (07934711) would be more than enough. But if you are after another serious investment, I absolutely LOVE my LeCroy (177-1268)

Keep tinkering!
