Hi everyone! I created this Halloween Cylon for this year's Halloween. I found a cool idea on https://www.evilmadscientist.com/2006/make-a-cylon-jack-o-lantern/. So it is by no means my own idea.
I did, however, make my version using an Arduino Nano V3. This article explaines how to do just that.
P.S. I am writing this article after I created the pumpkin itself so I don't have every step detailed with a photo, so bear with me. :)1) First I made a prototype
No pictures, see the schematic for this. It uses 10 5mm red LEDs with each an 330 ohm resistor. Each LED is is connected to a digitalPin.2) Solder the LED to a piece of cardboard
I used a piece of cardboard and poke holes in it for each LED and resistor.
I found a design online (https://www.wikihow.com/images/sampledocs/b/Cylon-Pumpkin-Stencil.pdf), but I wasn't too fond of it so I draw one (not to shabby if I do say so myself).
I used a piece of styrofoam to keep the leds in place by placing the leds between the styrofoam and the side of the pumpkin. I placed the other parts inside a ziplock bag and placed this inside the pumpkin
I am quite happy with the end result.
