Electronic Jack-o-Lanterns and Candy Bowls! #ElectronicHalloween
The Adafruit Learn System has some of the best halloween content out there! Here are just a couple of our favorite to get your #Electronichalloween off to a great start!
Jack-o-Theremin Make spooky, pumpkiny sounds this Halloween! A theremin is an electronic musical instrument that you can play without even touching it – spooky! The theremin senses the distance from its antennae to the player’s hands, and changes its pitch and volume based on these distances. The theremin was used to make soundtrack music for many iconic spooky movies, like The Day the Earth Stood Still (1958), and is perfect inspiration for a Halloween project!
Here, I’ve turned a pumpkin into a Jack-o-Theremin using an ultrasonic distance sensor and a Circuit Playground Express (CPX). The CPX uses the distance measurement to generate a sound and flash the onboard NeoPixels in various colors. This version of a theremin has a much more digital-bleepy-bloopy sound than a traditional theremin, but you still get to make music by waving your hand around in the air! Learn more!
Track Your Treats: Halloween Candy GPS Tracker Track your trick or treat candy route to log which houses had the best candy! So you’ve got an awesome Halloween costume planned, but do you know the best places to go trick or treating this year? Some houses have great candy while others might stick you with a set of wax teeth or a granola bar–yuck! Wouldn’t it be nice to keep a record of the best houses for trick or treating? With this Track Your Treats GPS Candy Tracker project you can build a candy container that logs exactly where you found the best Halloween candy. Using the power of the global positioning system you can optimize your trick or treat route for maximum candy acquisition! Learn more!
Halloween Pumpkin :
Here is a quick project for an electronic halloween pumpkin. With a bit of hacking a $1 plastic pumpkin is upgraded: a sensor embedded in the nose detects when people get close and will play scarey sounds and animates LEDs on the face. The sounds are stored on an SD card so it’s easy to change and customize what the pumpkin says, while the code is written for an Arduino so it’s easy to modify the behavior. I’m going to have this pumpkin outside my door to freak out the little kids who go to daycare nearby. Boo! Learn more!

We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
