How to Load and Save Configurations on an Arduino

September 26, 2017

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…

Arduino Tutorial: Using millis() Instead of delay()

September 5, 2017

Arduino Tutorials,

A well known Arduino function is delay() which pauses the program for an amount of milliseconds specified as parameter. millis(), on the other hand, is a function that returns the amount of milliseconds that have passed since program start. At…

What Is FFT and How Can You Implement It on an Arduino?
