weatherstation

IoT kurs med introduksjon til ESP8266, servo, 7-segment display og værapi.

Upcoming changes

• Configurable weather location through WiFiManager?
• PCB for easier connection etc

Excercises

1. Hello World
2. Hello Servo
3. Hello display
4. Hello WiFiManager
5. Hello Weather API
6. Combine everything you have learned!

Hardware

• ESP8266
• Microservo
• 7-segment 8-digit display
• laserkuttet deler

Software (3rd party libraries)

• WiFiManager
• LedControl for MAX7219 (either use the one from Library Manager and do the AVR fix (see below), or install modified library from Nikhil André Luthras GitHub repo here: https://github.com/9khil/LedControl)

API

• This course uses weather data from Yr.no, but with a custom endpoint that just returns the data we are looking for. Probably not usable for anything else than this. The endpoint has a 20 minute cache in place. Url: http://weather.labben.org/api/yr/?location=**enter location from yr.no** Example url: http://weather.labben.org/api/yr/?location=Norge/Oslo/Oslo/Oslo/
