Data Logging Zero to Hero with CircuitPython and MQTT #CircuitPython #MQTT @robmarkcole @HacksterIO

Robin Cole on documents a using data logging – going from zero to hero with CircuitPython and MQTT.  Using Python and open source software, it shows how to publish data from a sensor over MQTT, persist the data, and visualise it in real-time.

The purpose is to demonstrate a beginner friendly workflow that is not too complicated using CircuitPython, and demonstrates a solution that has real world applications – logging sensor data over a network, storing it in a database and displaying the data on a dashboard is what many IoT companies are doing (note, we are skipping security which is what you pay the companies for, as well as scale).

The project shows a number of Adafruit products listed at right.

The Python code required to read the sensor data and print it to the console is below:

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, 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.
