Build this candy bowl you can monitor remotely over a WiFi network so trick-or-treaters never leave your home empty handed. A simple infrared light sensor detects when the bowl is empty or full, and a CC3000 WiFi chip exposes the sensor data to your wireless network. You can telnet to a simple server running on the Arduino and ask it if the bowl is full of candy!
This tutorial is a great demo of using the CC3000 breakout/shield in server mode, and also with mDNS so you don’t need to know the IP address of the module!
HAPPY HALLOWEEN! Every day this month we’ll be bringing you ideas and projects for an Electronic Halloween! Expect wearables, hacks & mods, costumes and more here on the Adafruit blog! Working on a project for Halloween this year? Share it with us on Google+, in the comments below, the Adafruit forums, Facebook, or Twitter— we’d love to see what you’re up to and share it with the world (tag your posts #ElectronicHalloween). You can also send us a blog tip! Tune in to our live shows, 3D hangouts with Noe and Pedro and Ask an Engineer, featuring store discount codes, ideas for projects, costumes, decorations, and more!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
