DIY Projects for Halloween to Make a Spooky Town

Shadows of a thousand years rise again unseen, voices whisper in the trees ‘Tonight is Halloween!’

Finally, ‘tis the spookiest time of the year! And this time, we’re all set to redefine ‘spooky’ with the DIY Spooky Town where robots celebrate Halloween! For making this town we’re going to use what we made in some of the previous projects such as the DIY Turntable, Robotic Arm, Rat Trapper, Smartphone Controlled Robot, DIY Lightsaber, and 3D printed objects like the ones below!

And since October 26 is Pumpkin Day, we’re going to make a spooky DIY PIR sensor activated jack-o’-lantern to make the town eerier! Get ready for the most spooktacular project of the year this Halloween!

Ready. Set. Boo!

Step 1: Things You'll Need

evive
Bulb
Bulb Holder
Relay
PIR Motion Sensor
Thick Cardboard
Butter Paper
Colored Chart Paper
Jumper Cables
Electric Wires

Most of the above electrical components are present in the evive IOT Kit. There are number of projects on Instructables made with it.

Step 2: Making of the Pumpkin

We are going to make the pumpkin out of cardboard or you can use even a real pumpkin.

Take the cardboard and cut it in the shape of the pumpkin.

Stick the butter paper on the cardboard.

Now, stick the colored paper on top of it. Or the plain paper of its shape and then color it the way you want.

Step 3: Adding the Scary Touch

This pumpkin won't scare the people. We need something more.

Something like a glowing pumpkin when you go near it. Thus, to make it glow we need to add lights. We are going to use the bulb for this. Make a box out of cardboard if you do not a ready-made box. This box will be the house of the bulb and relay(switch).

Insert the bulb holder through the bottom side and insert bulb in the bulb holder.

Alongside the bulb place relay too. Glue this box on the backside of the cardboard.

Step 4: Hero of the Project

It's time to introduce the hero of the project that is the PIR Sensor. This is the one that will detect the presence of anyone near your pumpkin.

Attach the Sensor on the front side of the pumpkin and pass its wires through the hole. As we are going to make all the connection on the backside.

NOTE: If you are using a real pumpkin, you need to make sure that the Sensor is not covered.

Step 5: Final Touch-Up

Make the connection as follows.

And upload the following code.

Thus when PIR detects the presence of the human, the relay connected to the bulb gets triggered switching on the bulb. To make it more dramatic we are turning the bulb ON and OFF a number of times. Also, to add more effect, we have programmed the inbuilt buzzer in evive so that it will generate the spooky sound we want that syncs with the lights.
