Tutorials

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…

Avoiding Coincident Face Rendering Artifacts Using Dielectric Priority in Autodesk Fusion 360

March 5, 2019

This is a short tutorial on how to avoid unwanted rendering behavior for coincident faces in Fusion 360. However, this is a principle that probably will work elsewhere as well, given you have access to similar dielectric priority options. One…

How to Easily Model Wires and Tubes in Autodesk Fusion 360

January 14, 2019

In this blog post we’ll show you how to create wires and tubes in different ways. We’ll start with laying everything on a flat surface, then on an uneven surface and lastly mix things up a bit more. These methods…

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

Ragnar Ranøyen Homb

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…

Makefiles: Part 2 — Makefiles Can Make Webpages?

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…
