This is my 7 Segment display clock. The project started out as a rebuild of a project by Frugha on Hackaday. The display is built using 144 7 Segment displays controlled by an arduino nano.
I initially built the project exectly acording to the original schema, but quickly came up with several extensions and improvements to make make the clock more usefull to me.
- DHT22 temparature/humidity sensor
- Displays the room teparature once a minute.
- ESP-01 Wi-Fi Module
- Fetch the current time on boot-up from NTP.
- Re-sync the NTP time perodically.
- Display outside temparature, fetched from weather services.
- Display stock price for stocks in my portfolio.
- Add Home Assistant integration to turn of the display.
