We had yet another workshop/hackathon, this time focused on IoT, with moduls from bigclown.cz
We tested Core module kit (connecting gateway + node), which can bet programmed via USB DFU bootloader located in ROM memory or ARM microcontroller and/or debugged via standard 10 pin SWD connector. Core Module is key element of every BigClown node. On the “motherboard” there is integrated security chip, heat sensor and accelerometer. We also had external I2C modules – hygrometer, thermometer, modul with relay and controlling of RGB LED stripe.
It is professional solution not only for home automatization, and also an introduction to broader IoT usage. We went through basic installation, initialization and couple of simple experiments. After connecting Raspberry Pi3 to Raspbian and installing of control software we were able to use MQTT (widely used protocol for IoT)
mosquitto_sub -v -t ‘#
this command “prints” ID of distant node:
>> node/836d19836043/thermometer/0:1/temperature 22.50
LED demonstration:
mosquitto_pub -t ‘node/836d19836043/led-strip/-/effect/set’ -m ‘{“type”:”rainbow”, “wait”: 5 }’
For future we plan adding Python layer and integration with Cryptomat and advanced data transfer for visualisation and interaction in VR.
