  • EspOledTemp

    EspOledTemp is a little hardware device that I have built and designed myself. The goal has been to create a showcase for my knowledge in mainly electronics and programming. The base for this build is a NodeMCU, a Soc based on ESP8266. It has a sensor for temperature and humidity connected, a HTU21D module. It […]
