Whispering Wind
This is a clock with environmental information display I made using an ESP32, a GPS receiver, light sensor and temperature sensor. The code is open source as are the STL files for the 3D printed open frame case.
The github project includes a discussion on components I used and some potential alternatives.

I couldn’t find any on-line documentation on controlling the WT32-SC01 backlight brightness so I experimented. After some trial & error I worked out which pin controls the brightness & was able to write a few lines of code to achieve this.
As I spent some time doing this I thought I’d publish my code to save others some time. The project is on github
