To mark the release of Losant’s Python MQTT API client and REST API client, we will be constructing an Internet-connected two-man switch – think nuclear weapon launchers from the movies where two separate people have to turn a key – using a pair of Raspberry Pi 3 Model Bs. We’ll send the key-turned state of each device to the Losant platform using our newly released Python SDKs and, if all keys are turned, allow an action to take place when a button is pushed on either device.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
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.
