I was actually inspired by this project:
Evil Mad Scientist Laboratories
I liked the idea, but I really wanted to design my own circuit that I could switch on an off, and I wanted to use a different LED color and pumpkin size.
Step 1: Pumpkin Carving Materials
Step 2: Carve the Pumpkin
Once you're done, you'll have a tiny jack-o'-lantern that looks great by itself. But don't eat it, because we're going to kick it up a notch!
Step 3: LED Module Materials
- One (1) ultra-bright red LED (2.4 V, 20 mA)**
- One (1) 33-ohm resistor
- One (1) SPST switch***
- Two (2) AA batteries
- One (1) snap connector (typically used for 9V batteries)
- A four AA battery holder
*** You'll notice that later in the video I am actually using a DPDT switch. I had a lot of those, but I only had a few SPSTs.
