Coding

Lot of time, no progress.
I spent quite a long time trying to make buttons on my board work with my code. I couldn’t make them work :) . Instead of buttons I might make text change with specific a frequence.

3D-modelling

I started making box case for simple electronics (the board and battery case). I used Tinkercad for modelling. I had used Tinkercad before but it’s been long time since I used it last time. I really liked that Tinkercad has ready models of electronics even though it didn’t have the ones I’m using. That’s why I had to use components as close as possible to my actual components.

This project has now officially started. Git and github are set up and the core feature works! Currently the arduino (it’s actually Wemos, not arduino) is able to show current price.
 
I use free API to get spot electricity price (it’s price in Finland).

The board I use is Lolin D1 mini Pro V2.0.0
 

My plan for this project:

• make the screen display current spot electricity price
• design and maybe build box/casing for electronics
• add leds to indicate how cheap or expensive electricity is now
• add buttons for scrolling future prices
