An Arduino Nano 33 IoT based gadget which interrogates the latest tide height from your chosen UK measurement station.

The tide data is scraped from the Environment Agency website: https://environment.data.gov.uk/flood-monitoring/tidegauge/index.html#filter=7&station=E72639

The Bristol channel where the measurement is taken has the third highest tidal range in the world

The code is an amalgamation from the following sources

Nixie driver https://github.com/dekuNukem/exixe/tree/master

WiFi https://www.arduino.cc/reference/en/libraries/wifinina/wifi.beginap/

SSL https://www.arduino.cc/reference/en/libraries/wifinina/client.connectssl/

JSON Handling https://arduinojson.org/v6/api/json/deserializejson/

Project Code

The code is here: https://github.com/bigcrimping/tide_meter/tree/main/code/wave_height_0.2

You will need to add your WiFi details to the arduino_secrets.h file for the network you wish to connect to.
