Engineering a Battery Powered Wifi/BLE Smart Lock with custom PCBs

2021-09-10

I wanted a smart door lock, so i tried to build it myself with an ESP8266 and a JDY23 Bluetooth LE Module.
My journey to meet my expectations was a lot longer than expected, but see for yourself.
This project was hard, but i learned a lot!
