Introduction: Skull With Flashing Eyes
For robotics class, we needed to make a Halloween decoration with flashing LEDs. This is a cheap project that will cost you less than $10 and is really easy to build! This will make a good Halloween decoration for your house.
Step 1: Parts and Equipment
To make this project, you will need:
- Velleman MK 102 Flashing LED Kit
- Two Breadboard Jumper Wires (link to buy 40)
- Battery Holder (link to buy three)
- Halloween Prop. For this project, we will be using a skull. You can usually find these at a local store.
- Soldering Iron
- Wire Cutters
- Safety Goggles
Step 2: The LED Kit
The first thing you need to do is assemble the LED kit. This is the only time you will need to solder. The instructions should explain everything you need to do. Do not do step five yet. You will have to assemble the LEDs later in the project.
On step six, instead of installing the included battery holder, use the battery holder that we bought for this project and use that one instead.
Step 3: The Skull
Once you are done building and soldering the LED kit without the LEDs, you will need to open up the skull so you could put the electronics inside the skull.
Cutting a hole big enough to fit the LED kit inside of the back of the head will do the job. You will also need to use a drill to make holes inside of the eyes of the skeleton for the LEDs.
Also, make sure to put in batteries before putting the LED kit inside the skull.
Step 4: Installing the LED Kit Inside the Skull
Now you are ready to put your LEDs in. Connect the breadboard wires to the circuit and feed them through the eyes first. After that, attach the LEDs to the wires that are sticking out of the eyes. Make sure to place the LED's longer lead into the red wire.
Step 5: Done!
Once you've stuffed the whole LED kit inside of the skull, you are done! All you need to do is turn it on from the battery holder.
