From the early start as a complete ‘noob’, this blog mainly follows my tinkering activities on Arduino, Esp8266 and Esp32 microcontrollers. Apart from using these boards for reading sensors, controlling actuators and transfering data, I also like the challenge of writing (often math inspired) programs for their relatively limited resources.
In most cases, a proof of concept (preferably solderless) will do for me.
