Here we are with another tutorial on Arduino programming. This time, we will look at static variables and how you can use them to your advantage. What is a Static Variable? A static variable is a variable that stores its data as long as the program is running. Consider a …

Last time, I showed you how to send HTTP requests via TCP featuring the ENC28J60 ethernet shield. We continue with our series with another post, this time, using JSON for data transfer. Full tutorial after the jump.

If your Arduino code involves decision making, then it’s very likely you’re using conditional statements. Using if … else… is common;  switch statements can be used as well. But there is a third way, using ternary operator, that will really make your code shorter. Example Scenario Say we are reading …

The Arduino platform runs on C++ and with this comes all the pros (and cons) of the language. One of those pros is the use of classes and in general, object oriented coding. This article aims to guide you in creating your own Arduino classes which can make your sketches …

An array is a data structure for storing multiple variables of the same data type. Mastering arrays will definitely make your Arduino sketches more efficient. If you’re a beginner when it comes to Arduino array, then this tutorial is for you.

Description FastLED is a fast, efficient, easy-to-use Arduino library for programming addressable LED strips and pixels such as WS2810, WS2811, LPD8806, Neopixel and more. FastLED is used by thousands of developers, in countless art and hobby projects, and in numerous commercial products.

If you read sensors using microcontrollers before, you have dealt with data that is always moving above or below a set point. This “noisy” data can be processed using a moving average filter.

This is a short note on implementing the Bubble Sort algorithm on the AVR and Arduino microcontrollers. Bubble sort or sinking sort is one of the many sorting algorithms. In this algorithm,  a list is repeatedly read where each line is compared to adjacent elements and swaps them if they …

  In this IoT age, there are several ways of sending and getting data to/from a microcontroller to a remote server. This article will be the first part of a series about such ways through the Arduino ENC28J60 shield or module. Here I will be showing the classic way of …

An Arduino’s EEPROM, depending on the type of board, can store up to 4 KB of data. The Arduino UNO, in particular, stores 1024 bytes or 1024 ASCII characters. With that space, how can we store a sentence? Or a paragraph? This is what this article is all about.
