Since the corona virus I have become increasingly aware of my environment. I also started to delve deeper into my living environment and in particular the air quality. I Already wrote a blog about the NASA Clean Air Study, this blog explains how you can clean your indoor air with plants. But I don’t know how […]

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

Through some researches I did online on how to minimize components use, I stumbled with using an ATTiny13A chip to be used in the project. And through some more researching, I decided to have my new project done using the ATTiny13 Chip. ATTiny13 Chip I bought these chips from Ali-Express. First I need to study

The I²C bus communication is one out of three possible communication protocols, the ESP8266 is able to communicate with other devices like OLED displays, barometric pressure sensors and so on. The two other communication protocols are SPI and UART. I²C stands for Inter-Integrated Circuit was invented 1982 by Philips Semiconductor (A Dutch company), now NXP
I have only started electronics as a hobby and it has been a great learning resource for me so I am far from any type of expert. But I like to share my knowledge. I wanted to change the logo on my OLED display. It took me days to work it out thanks to very
