Voltage is one of the fundamental values when dealing with electronics. It determines the amount and direction of current flow and represents the potential (electric charge) difference between two points, thus it is somewhat impossible to build or troubleshoot electronics circuits without...

2 Channel Relay Shield for Arduino UNO is a simple and convenient way to interface 2 relays for switching applications in your project. The board has been designed using large current relay that can handle a load up to 30Amps. Relay circuit is optically isolated to prevent any kind of...

Fingerprint sensing is one of those technologies in science fiction movies that fascinated most of us as kids. Today, they are everywhere and asides from existing in everyday devices with huge electronics complexity, like mobile phones, they are also available in tiny modules to give...

Visualizing data when working with the Arduino is something we all have had to do using third party/ self-developed software in the past. It was thus, it is really interesting when the Arduino team decided to change that recently. Today, we are going to take a look at their solution,...

Displays are one of the best ways to provide feedback to users of a particular device or project and often the bigger the display, the better. For today's tutorial, we will look on how to use the relatively big, low cost, ILI9481 based, 3.5″ Color TFT display with Arduino. This...

Introduction While building microcontroller based projects, there are occasions where communication will be required between two devices, either in a duplex/transceiver based operation (where both devices can transmit and receive at the same time) or in a simplex-based operation where...

Time is a critical element of our existence that will never get old, and with technology, we can find better and more intuitive ways to measure it. In one of our past tutorials, we looked at how the DS3231 real time clock module can be used with Arduino to display time on a 16x2 LCD...

As the popularity of Arduino boards increased, the demand for boards which comes embedded with some of the add-ons used with the Arduino increased. One of the most popular add-ons were the WiFi modules which are used to connect Arduino boards to the internet. Several boards were released...
