The contributors to the book introduce themselves here.
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). You can find the code for some of my projects at github More recently, I started a blog (in English) about my experiences with the Raspberry Pi Pico (and other boards based on the RP2040 and the RP2350). 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; the results (so far) are Knowing the RP2040 and Using Sensors with the Raspberry Pi Pico.
