I write about using C, 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 how to program the RP2040 or Atmega328P.

Courses

• C: Developing in C on the AVR ATmega328P: Learning How to Develop C Code on the AVR family of processors
• C: Developing in C on the RP2040: Learning How to Develop C Code on the RP2040
• Electronics: Testing using the Espotek Labrador: Learning to use the Espotek Labrador to analyze circuits.
• Forth: Mecrisp-Stellaris Forth on RP2040 or FlashForth on the ATmega328: Learning Forth using the RP2040 (Raspberry Pi Pico) or the ATmega328P (Arduino Uno).
