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...

Introduction Over the past few tutorials, we have mentioned several scenarios where using any of the Arduino board in a project may be an overkill due to the cost, size, and more technical reasons such as high power consumption. In the last tutorial, we discussed an alternative way of...

Introduction Cost and size, just to mention a few, makes using an Arduino board in certain projects an overkill, often times its always too big, or too expensive for the scope of the project especially when it's a project that we need to make several units. One good way to retain...

Smartphone’s camera detects your face and the fan moves automatically according to your face. This is an easy project using obniz, servo motor, smartphone, and a fan. Required Components Obniz Servo motor Small USB fan USB <-> Pin header Pin header...

Over the past few tutorials, we explored several ways to further reduce the power consumption for Arduino based projects so they can last for a long period of time running on the inexpensive AAA batteries. We have tried different approaches like the more recent tutorial on using...
