porno bichAs 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…
porno bichAs 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…
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…
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…
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…
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…
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(). We mentioned one caveat with…
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…
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…
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…
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…
Using Arduino to simplify programming is nothing new. There are Arduino libraries for almost everything, and with one or more of these in hand you can make awesome gadgets, even as a clueless beginner. Programming LEDs is no exception, and…
In almost every Arduino tutorial we’ve written we’ve used serial output for either printing text to terminal or plotting values. It is also invaluable as a debugging tool. We have rarely written about serial input, however, which is what this…
Previous parts of the Getting Started with Programming series: Part 1: Skimming the Surface Part 2: Conditional Statements Part 3: Loops Part 4: Arrays and Lists Part 5: Functions and Scope Part 6: Defines and Random Numbers Part 7: Pointers…
We have earlier written a rather deep post about a non-volatile (not lost when power is) way to store data here, but in this post we will focus on the following question: How can I save and load configuration data…
