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!
Before you get started it will help to familiarize yourself with the CC3000 and IR sensors by reading these related guides:
