Alain Pannetrat recently wrote a blog article in which he shows how he found a bug in the implementation of the Arduino analogRead() function for the SAMD21.
In this video, I show how to decode a single-byte UART communication between my computer and my Arduino Uno.
I do this using my Rigol 2072A bench-top oscilloscope, and a Loto Instruments OSC482 “virtual” or “PC” oscilloscope.
Over the last couple of months, we’ve been working on a major update for our website.
With this update, we aim to modernize the user interface and to make your learning experience more efficient and productive.

ESP32 Unleashed is a project course. The structure of the course resembles my development process. My development process, whether it is a course, a gadget, or a book, or fixing the washing machine, looks like this: Set the overall objective (what am I trying to achieve?) Set plan (how am I going to achieve my […]
In ESP32 For Busy People, I have a section on the SPIFFS, the SPI file system. In this section, I show you how you can upload a file (like an image, or a text file) to your ESP32 and then use it in your sketches. One thing I did not show was how to retrieve […]
In this article, I write about my top six reasons why I decided to learn how to use PlatformIO (in no particular order).
We are placing the final touches on a new course, titled “ESP32 Unleashed”. In this course, I’ll show you how to use the ESP32 dev kit to make a gadget that contains sensors, a touch screen, a custom PCB (no loose wires!), and Cloud services (you can even speak to it!). The real “kick” is […]
The previous PCB, v1.1, worked well “out of the box”. But I wanted to include more information about the various pins and their roles by adding text in the silkscreen. In this post, I describe the features of the new version of the PCB.
Early in May, Leo, Ari, and myself drove south, to the regional airport at Albion Park. It was a special day. Aircraft, old and new, were on display. On the ground, and in the air. This was our second visit. The first one was last year. Wings Over Illawarra is perhaps the best airshow in […]
