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!
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.
