DOORBELL MODERNIZR

The Doorbell Modernizr is based upon the popular ESP8266 microprocessor. If you like, you can program it yourself with your own software, for instance with the Arduino IDE. To program the module, you need an FTDI module to program it through USB. There's a header on the board to plug the module into. On the board you can find a small "program" switch. To program the module, plug in the FTDI module, set the switch to "on" and apply power... Doorbell Modernizr from Lemcke Solutions on Tindie
