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.
It was a few minutes before midnight when the security alarm of our neighbors started whaling. It happens all the in our neighborhood, and nobody pays attention anymore. However, that night, I was alone in the house with our baby, so I took a nervous peek through the window. And there it was. Three men […]
The unit “baud” is the speed of communication between the two devices. Your computer and the Arduino talk via the USB/TTL (serial) interface. There are a few parameters that control this communication, but all of them are standardized (so you don’t have to worry about them) except for the speed. If you don’t set the […]
To understand what happens when you give a negative PWM value to analogWrite we need to look into how the Arduino deals with negative numbers, and how those are used in the PWM function. The following contains some binary logic terms that you may not be familiar with, so I am sorry if I am […]
Saturday, May 12, was Arduino Day 2018. Marcus, founder of Little Bird Electronics and I took the opportunity to do a live webinar in which we answered questions from our friends in the audience about the Arduino, e-textiles, Raspberry Pi, and lots of related topics. It was a lot of fun, and we hope to do more […]
The Arduino Bootcamp for Teachers is now in its third month of operation! The Bootcamp is a fast-tracked program in which teachers can learn the skills needed to be able to use the Arduino as part of a STEM curriculum, or to teach the Arduino to their students as an independent topic. My team and […]
I have designed this Arduino project course as an opportunity for you to get deep into the messy details of understanding, designing and constructing a simple yet infinitely extensible wheeled robot. From figuring out what the robot is supposed to do, to selecting the right parts, configuring them, assembling them and testing them, all the […]
The retiring of Arduino SbS Your Complete Guide, and introduction of Arduino SbS Getting Serious has given rise to a few questions among our students. In this post, I will try to answer those questions. Always, feel free to get in touch. If you are a student of Arduino Step by Step Your Complete Guide, I […]
