Arduino Tutorials

As shown in this blog post; we created a simple command line interface (aka. CLI) for the Arduino. It was not optimal when it came to things such as memory usage or code size, but the main goal of the…

Arduino as a Stepper Motor Controller – Jogging with acceleration

August 28, 2019

As we have written about earlier: Jogging a stepper motor with an encoder can easily be accomplished with an Arduino. In this post will we show how a simple “stepper motor jogging-system” can be enhanced with acceleration and de-acceleration. Introduction…

Using a simple Arduino to measure capacitor value

August 14, 2019

As you probably read in this post, capacitance is a measure of the ability to store energy. They are among other things used in rectifiers, as bypass devices and in analog filter circuits. They are super-important components and critical for…

Arduino as a Stepper Motor Controller – Speed and Position Control With a Potentiometer

June 26, 2019

Not long ago, we published a blog post related to this topic. The difference is that the previous blog post used a rotary encoder to jog the stepper motor. This time we’ll swap out the rotary encoder with an ordinary…

Arduino as a Stepper Motor Controller – Jogging Using a Rotary Encoder

May 29, 2019

In this post we’ll show you a simple example on how to use a rotary encoder to move a stepper motor in real time, aka. jogging. This will be done using a standard stepper motor driver, but without any shields…

Arduino FFT pt. 2: Improving the Hardware for Real-time Analysis

March 20, 2019

One and a half year back we wrote an introductory blog post about FFT and Arduino, which today is one of our most popular blog posts. This time we’ll upgrade the hardware to a Teensy 3.2 and see which advantages…

Arduino Tutorial: Avoiding the Overflow Issue When Using millis() and micros()

October 11, 2018

One of our most popular blog posts right now this is called Arduino Tutorial: Using millis() Instead of delay(). Here we discuss how to use millis() and micros() and their major advantages compared to delay(). Not a great analogy to…

Controlling a Camera Shutter Remotely with an Arduino

July 20, 2018

Arduino Projects, Arduino Tutorials

To take a picture on the exact moment you want to can be a hassle. But most cameras have the possibility to use an external shutter remote. Connecting a regular button here does not help us, but by creating a…

Arduino Tutorial: LCD Displays pt. 3 – Graphic Displays

April 26, 2018

Previous parts in this series: Part 1 – HD44780 Character Displays Part 2 – The Serial Backpack The next natural step in this series is arguably some kind of graphics display. We looked around in our gadget inventory and found…

Arduino Tutorial: LCD Displays pt. 2 – The Serial Backpack

March 8, 2018

Last summer we wrote a blog post (which we recommend reading before continuing) about how you can hook up an HD44780 character display to an Arduino and program it using the LiquidCrystal Arduino library. Back then we had to use…

Creating a Command Line Interface in Arduino’s Serial Monitor

February 2, 2018

We briefly touched upon this topic in our post about Arduino serial input, but inspired by this excellent tutorial by Stephen Brennan we thought it would be fun to create a more rigid command line interface (aka. CLI) for the…

Programming Digital RGB LED Strips with Arduino and the FastLED Library
