Microcontrollers

Fluid Networks workshop is using at least 3 different boards, two microcontrollers (MKR 1010 from Arduino, and lately Wio Terminal from Seeedstudio) and a Single Board PC, namely a Raspberry PI (running Node-RED)

Examples for Wio Terminal¶

After introducing the different parts of the kit, we started discovering the different uses of the board and of Arduino code using Tinkergen (online).

Later, we primarly focused on making the board connecrting to the internet, sending readings in JSON format, using MQTT, also using the screen.

Examples (for MKR 1010)¶

Most examples start with a number, and are willing to give a concise and self-explanatory guide to use the sensor with the corresponding board of the kit hookoed up with the MKR Connector Carrier-
