I write about using MicroPython and Forth with microcontrollers as well as practical electronics and inexpensive test equipment. Use Courses below to follow a specific learning path on using the Espotek Labrador or learning Forth on the RP2040.

Courses

Electronics: Testing using the Espotek Labrador: Learning to use the Espotek Labrador to analyze circuits.
Forth: Mecrisp-Stellaris Forth on RP2040: Learning Forth using the RP2040.
