For those who follow my blog know that I have a 3D printer. Besides thinking up and creating everyday solutions with my 3D printer, I also like to draw 3D models. In this case the 28BYJ-48 Stepper Motor. By drawing 3D models I learn “playfully” more and more. I sometimes made models in the past, […]

The upload procedure for ESP8266 boards is a little different from a standard Arduino procedure. Most Arduino’s will automatically reset when a new program is being uploaded, and will automatically enter programming mode. On some ESP boards you have to manually enter programming mode, and on the bare-bones modules, you even have to reset them

Slowly but surely I am looking at the extensions of the “standard” ESP HomeKit accessories, how to implement them. Now I am working on the Battery status. We need some circuit which can effectively measure voltage. Battery monitoring circuit is a traditional voltage divider circuit. I am going to measure 3.7 volt (lithium Polymer) battery.

The “WEMOS D1 Esp-Wroom-02” that I got from Ali express is another micro controller development board with an ESP8266 WiFi chip. The board has an integrated 18650 battery charging circuit. There is also a board that has an OLED screen and a directional button built-in. This makes the board an excellent option for mobile applications. And like all
