4 inch display wall case

thingiverse

It is enhanced version of my previous design here: https://www.thingiverse.com/thing:4187560 Now you can mount it to the wall easily. There is enough space for USB cable inside(so you can power it up from behind, no cable will be visible). Fusion360 file attached if you want to edit it, arduino code is also attached, just rename it from .txt to .ino and upload it. You can find how to connect everything in arduino code(pinout section). there is some picture at top right corner so if you want some picture there, you will need upload that image to SPIFFS first. It will measure difference between two dates, you can set it up through built in touch Menu. It is driven by ESP8266(nodemcu), so WiFi is also available(i am not using WiFi in attached code, for settings i am using tft touch Menu). For time stuffs there is RTC DS3231 module with rechargeable LIR2032 battery(do not use normal battery as RTC module is slightly charging that battery).
