The STM32F4 microcontroller series is popular in embedded systems applications due to its powerful features. One of its key peripherals is the Digital-to-Analog Converter (DAC), which enables the generation of analog waveforms. In this article, I will show you how to generate sine, triangular, and sawtooth waveforms using the STM32F4 …

We’ve featured in a previous project how we can make a “plant” send messages when it needs more water. Of course, healthy plants don’t only need water; the soil in which they are planted must also be abundant in a number of chemicals. Is there a sensor that does this?

End your search for the ultimate, cost-effective IoT starter kits designed to help you construct innovative IoT solutions. With these exceptional smart device kits, your journey into the world of IoT begins here. The Internet of Things (IoT) represents the future of technology, a sector poised to attract billions of …

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 part of a series about such ways through the Arduino ENC28J60 shield or module. Here I will be showing the classic way of communicating via the …

Labcenter Electronics’ Proteus has become an indispensable tool for engineers as it offers not only schematic and PCB design but also real-time simulation. However, Arduino simulation is not supported by this application by default. This tutorial will show you how to simulate an Arduino with Proteus ISIS.

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 …
