Interactive Halloween props are always fun and they are surprisingly easy to make. This year I designed a simple system that rotates a skull to face you and follows you movements as you walk by. An Arduino microcontroller then calculates where they are standing and activates a servo that turns the skull to face them. When they move, the skull turns to follows them.
The first thing that you need to do is select a Halloween prop that will turn and follow people walking by. Look for props that are both creepy and light weight. I chose to use a foam skull but there are a lot of other props that can also work. Use your imagination. The brain of this project is the Arduino UNO microcontroller. This board has six analog input ports that are used to measure the voltages coming from the light sensors.
The Arduino monitors these voltages over time and calculates which sensor experiences the greatest drop in voltage. This typically results from a person walking in front of that sensor and casting a shadow on it. The arduino then activates a servo to turn the skull to face that sensor and the person standing in front of it. A value of changes the average value slowly.
Now you need to connect the servo to the Arduino. The servo has three wires. The ground wire is typically black or brown. This should be connected to one of the GND pins on the Arduino. The signal wire is typically yellow, orange or white. This should be connected to one of the digital pins on the Arduino. The positive power wire is typically red. This needs to be connected to the 5V pin from the Arduino.
Unfortunately there is only one 5V pin on the Arduino and that is already being used to power the light sensors. So you should connect this wire to the positive positive power rail on the breadboard. The code that I included has several variables that you can change to adjust the performance of the skull. You can adjust the sensitivity of the sensors.

You can change how quickly the system re-calibrates itself to changing light conditions. You can set the time delay before the skull resets its position.
Try making adjustments until it performs the way that you like. My name is Jason Poel Smith. I have worked in a variety of industries from hydraulic aerial lifts to aircraft tooling. I currently spend most of my time chasing around my new baby. Thank you for this! I adapted it to rotate an eyeball inside a small pumpkin, and it turned out awesomely. Thank you so much!
Love the idea but wont it require quite specific lighting to work best? How would it perform in ambient lighting with multiple light sources?

To accomplish this, I first embedded magnets inside a severed hand prop. Then I took a second set of magnets and attached them to the end of a linear motor. This motor was mounted to the bottom of a table, and when the hand is placed on top of the table, the motor uses the magnets to move the hand. This process can be controlled manually or with various sensors and a microcontroller.
View this project on Instructables: instructables. In most cases, you will want to use sensors to automatically activate the motor — I chose to use a motion sensor. To hook it up, I simply connected the four wires from the motion sensor to the trigger terminals on controller. Each terminal on the controller is color coded, so just attach the wires to the matching colored terminal. When your friends reach for the candy bowl, the hand with slowly reach out towards them.
This will scare a lot of people simply because they weren't expecting it to move. My name is Jason Poel Smith. I have worked in a variety of industries from hydraulic aerial lifts to aircraft tooling.

My little ones and I are obsessed with anything and everything Harry Potter. When I came across these floating candlesI put them on my list without hesitation. They really remind me of the floating candles in the Great Hall, and totally worth giving a go.
The icing on the cake for these little gems is that you get to use your glue gun, and I take up any opportunity to whip that bad boy out!18 SPOOKY HALLOWEEN IDEAS YOU CAN DIY IN NO TIME
I also like any way to recycle everyday things with crafting, and in this case toilet and kitchen paper roles! Vanessa is a mom of two and total craft queen when she has time.

They would look great as additions to your Halloween mantle displays, as well as decorations for a Halloween party buffet. Trisha also has a few other ideas for spooky mason jars on her page, so definitely have a look at them as well. Trisha posts about crafting, food, lifestyle and a whole host of other things on her site MomDot. She also has some gorgeous free printables, which include colouring sheets for kids, beautiful quotes for framing, handy lifestyle hacks and loads more!
I love how tactile they look, with the raised lettering and the addition of plastic skeletons, bugs and other cool stuff. The choice of colouring almost makes it look like they were bound with skin, which totally gives me the creeps! Tara from Spot of tea Designs shared this super cool Halloween craft on Wholesale Party Suppliesthis was one of 8 things she made for a Halloween party, check them all out here. These would look great in a bush next to your front door, to creep out the neighbourhood kids and make their parents laugh.
I love how creative it is, and although it might take you a little time to get it right, I think the cool effect it has is really worth it.
This was shared by Micki Hares, over on Grillo Designs. She, and the cool people that submit their own creative ideas, will show you how to upcycle your home and everything inside!
Definitely worth a look and a bookmark! Out of all the props I feature on this list, this is the one that will have your kids, your grans and your dog running from the room screaming! Instructables is a great site to find exactly how to make pretty much anything, be it cute gift cards or horrific dismembered head in a jar illusion.
These bat decorations are really easy to make using just paper, but look really cool and effective. I love the freedom you can have with it. You could make just a few to compliment a Halloween display, or make loads to sweep across a room like a swarm of bats!
I like how in her pictures she uses the standard size but also a smaller one, for a bit of variety. Why not go crazy and make lots of different sizes? This could give you a cool false perspective effect, making the swarm look much denser and not so flat. She even has her own shop where she sells her absolutely gorgeous clothing and accessories. The first thing I thought when I saw this cool DIY Halloween prop was that it would be absolutely perfect as a centre piece for a spooky Halloween buffet table!
But I think you could adapt this to make a series of pedestals, all with different Halloween creatures and characters.The first thing that you need to do is select a Halloween prop that will turn and follow people walking by. Look for props that are both creepy and light weight. I chose to use a foam skull but there are a lot of other props that can also work. Use your imagination. This project uses an array of light sensors to detect where a person is standing.
I used CdS photoresistors but you could also use phototransistors. Even if you purchase a set of photoresistors that are the same type from the same manufacturer, the output of one photoresistor can still be very different from the next.
There are several ways that you can compensate for this. Another option is to change the Arduino code to compensate for different values of the photoresistors. You can add in a simple adjustment factor to any inputs, or you can write code that calibrates itself by referencing its average value. The brain of this project is the Arduino UNO microcontroller.
This board has six analog input ports that are used to measure the voltages coming from the light sensors. This typically results from a person walking in front of that sensor and casting a shadow on it.
The arduino then activates a servo to turn the skull to face that sensor and the person standing in front of it. To be able to turn your prop you need to attach it to a servo motor. How you attach your prop to the servo will depend on the geometry of your prop. Try to find an area where the servo can be easily hidden. If people can see the servo, it will be less impressive. The skull that I am using has a flat recessed area on the bottom behind the jaw. This made a convenient place to mount the body of the servo.
To attach the servo to the skull I applied a generous amount of hot glue to the bottom of the servo and pressed the two together for several minutes. Then I applied more hot glue around the edges.
To mount the skull and servo, I attached the rotor of the servo to piece of cardboard that will act as the base. First make sure that your servo is in the center position. This will make sure that it is oriented properly and can go through the full range of motion.

I applied hot glue to the center of the cardboard and to the rotor. Then I pressed the two together for several minutes until the glue hardened.
To make it a little more secure, I applied more glue around the edges. To assemble the photosensor array each CdS photoresistors is wired in series with a fixed 10kohm resistor. The center pin is connected to an analog input of the arduino.
This forms a light sensitive voltage divider. As the light changes, so does the resistance of the photoresistor. This results in a change in voltage at the center pin that is detected by the microcontroller. I used five of these sensors in this project. But you can use as many sensors as you have analog input pins on your Arduino.In this project, I show you how to use magnets to make Halloween props on a table move without anything touching them.
To accomplish this, I first embedded magnets inside a severed hand prop. Then I took a second set of magnets and attached them to the end of a linear motor. This motor was mounted to the bottom of a table.
When the hand is placed on top of the table, the motor is able to move the hand with the magnets. This process can be controlled manually or with various sensors and a microcontroller. The first thing that you need to do is embed a magnet in your Halloween prop.
So start by deciding where in the prop the magnet should be located. This should be some place that naturally sits flush against the table when it set down. On my hand I decided to mount the magnet on the inside of the wrist just past the cut end. Then take a knife and cut a slit in the side of the prop that is just big enough to fit the magnet. Then put a small drop of glue inside the cut slit. Then insert the magnet. You may want to place a small amount of glue on the outside to help close up the seam.
To help hold the magnet and the side of the prop together while the glue dries, I placed two more magnets on the outside of the prop. This held the magnet tightly against the inside wall of the prop. Allow the glue to completely cure before doing any further work with it. Now you need to attach magnets to the end of your linear motor. The number of magnets that you need to attach will depend on how thick your table top is.
If the extending rod on the motor is magnetic you may be able to simply stick the magnets onto the end and let them hold themselves in place. In my case, the rod was aluminum, but mounting pin was steel. So I just stuck the magnets onto the mounting pin.
In some cases you will need to use a different method of attaching the magnets. Glue will usually do a good job of holding them firmly in place. I recommend trying temporary glues such as hot glue first. That way you will be able to disassemble it after Halloween and reuse the parts.
Another option is tape. Tape will usually work but can leave a sticky residue. Next you need to mount the motor to the underside of the table. How you do this will depend on the type of table that you are working with, and how permanent you want the setup to be.
The most secure method of attaching the motor is to bolt it in place with metal brackets. However, this requires you to drill holes in your table. If you don't want to damage your table, you have two alternatives. One option is to replace the table top with a cheap board that you don't care about messing up. In my case, I replaced the table top with an old bulletin board.
This also had the advantage of being thinner than the original table top. Unfortunately, this method only works if your table top is detachable. The other option is to use a non-destructive method of attaching the motor. The best methods for attaching the motor without hurting your table are either hot glue or tape. Both of these have their limitations and they will not stick to all surfaces.Do you know where your DIY projects are?
