Check out this preview video of reverse engineering the protocol for a Bluetooth low energy controlled light bulb. Using the Bluefruit LE sniffer I can spy on commands sent by the light bulb’s control app and reverse engineer the protocol for controlling the bulb. After I have the protocol figured out it’s easy to control the light myself, like cycling it through all the colors using a Raspberry Pi and Bluetooth low energy USB stick. More to come in a future learning system guide!
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.
