This year I made 2 different Halloween IOT props. I used the same or similar techniques from the previous years... Actobotics for building out the structures and support, Particle.io for the IOT controller and software side, and pneumatic powered "mechs" from FrightProps.com for the movement. The new addition this year was adding in a FrightProps "Picoboo" controller to the setup, which brought on great possibilities. Adding this allowed me to add in audio and instantly cut power on and off...
