Halloween would not be complete without some novel electronics to spook the trick-or-treaters. Noel Portugal created a system that allows you to send text messages or tweets to his Halloween Candy Dispenser to drop some treats into your bag. Commands are relayed from the web via the ioBridge IO-204 to his microcontroller controlled candy dispenser. There’s a big red button in case you forgot your mobile phone in your Iron Man costume.
Noel wrote a web application using Oracle Application Express that connects all the parts together. At the heart of the design is an Arduino-based microcontroller that drives the servo-based dispenser mechanism. The commands are relayed from the web app to the Arduino using the ioBridge IO-204 via XBee radios. The Internet connectivity part is what allows tweets (@tweetfortreats) or text messages processed by Twilio to control the candy dispenser. The web application makes use of the ioBridge Widget API to parse commands from the Internet.
Just think of where this type of technology can go? Vending machines?
If you are interested in learning more, Noel has put together an Instructables so others can create their own DIY Halloween project this year. There’s also more information on Adafruit, MAKE, Hacked Gadgets, and Noel’s My Web of Things blog. Happy Halloween!
