Since you have clicked on this I'm guessing you want to make a fun, halloween inspired decoration that will not break the bank. That was the assignment my robotics teacher gave us and that's exactly what this entails.
A quick list of needed supplies:
- solder iron and solder
- your color preference of two led's
- 3 resistors
- 2 capacitors
- 2 transistors
- battery pack that can soldered on
- led extension cables
- motherboard thats applicable
- any halloween orientated object that has cargo space for these materials
- drill or awl
Here are the links to needed parts: https://www.amazon.com/Foxnovo-Breadboard-Jumper-... https://www.amazon.com/Foxnovo-Breadboard-Jumper-...
The tools can be found at any Home Depot or Lowes. I got the prop at a dollar store but I'm sure they sell similar at party city and stores of that kind.
Solder all the components on to the board. If you don't know how to solder there are youtube videos should give you a basic idea.
Poke or drill holes in the prop with a drill bit or awl. insert the led lights into this spot. I put them where the eyes were as this makes the most sense but put them wherever you think will work best.
Now for maximum attractiveness hide the components somewhere in the prop so they cant be seen. My prop is a cup so doing this was easy. If your prop does not have a ready made place to store this you might have to get creative. A knife can be used to make needed space.
All in all this fun project should not cost more than 20 dollars and it shouldnt take more than a couple hours.
