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 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 state 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.

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.

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 …

The Arduino platform supports math functions like sine, cosine, logarithm, exponential, etc. But can it solve higher math problems like calculus? This two-part tutorial will show you how to make a sketch for Arduino integrals and differentials solver.

Pointers can be confusing to beginner Arduino programmers. This tutorial aims to help you understand the concept of pointers by looking at software and hardware points of view.

Structs (short for structure) are far less common in Arduino programming because they are mostly used in C whereas Arduino is based on C++. However, they are still a very useful tool especially if there is a need for a user-defined data set. This tutorial aims to help you understand …

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. You may need to read about functions and classes before going through this one. What is a Static Variable? A variable is known to …

Most customers like to compare all products and services before they make a purchase. Often, this is done to ensure that the customer is comfortable with the product or service and that they have developed a full desire for the item. It is no different when choosing a mobile phone …
