  • Which MCU should I use?

    Nowadays there is a seemingly infinite stream of fancy microcontrollers to use for your new project. nRF? ARM? ESP32? PIC? How to decide?Here’s a handy list of a few common microcontrollers/modules! I’ll only be reviewing ones that I have experience using, as there are far too many MCUs out there for me to compare them…

  • Digital interfaces: explained

    Interfaces and protocols can be quite confusing for people taking their first steps into electronics and Arduino, but they are just like the languages spoken by microcontrollers and sensors. If two devices support the same interface, they can “speak” to each other with digital signals of ones and zeroes. Over the years, many different and…

  • An idea, a breadboard, and 3 hours

    One afternoon, I decided to make a project I had been thinking about for a while: a simple countdown timer. It would have been easier to just overkill the thing with a RPi Pico (32bit MCU) in 2 seconds, but I wanted to challenge myself and do it with an ATtiny, an 8 bit AVR…
