About the Author

Daniel Quadros

Hi, my name is Daniel Quadros.

I am an Electronic Engineer, but I have always worked as a software developer. Hardware is a hobby for me, and for the last two decades, I had a lot of fun with microcontrollers and participating in the Garoa Hacker Clube.

I have a blog and YouTube channel, both in Portuguese (I live in Brazil).  More recently, I started a blog (in English) about my experiences with the Raspberry Pi Pico (and other boards based on the RP2040).

In the 80s I wrote a few books about programming the IBM PC in Assembly language. It took me a long time, but I've started writing books again!
