This tutorial will guide you through the basics of controlling an Arduino at a low level using port registers and bit manipulation. We'll end with a practical example of blinking an LED using direct ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

LED Blinking: We use an LED (Light Emitting Diode), which is connected to the Arduino via a resistor. The resistor limits the current that flows through the LED to prevent it from burning by too much ...

It's easy to think about tinkering around with Arduino, but take more than 30 seconds to look at the platform, and suddenly it becomes daunting: not only do you need an Arduino itself, but to get ...

Arduino RFID technology works by using electromagnetic waves in the radio frequency spectrum for wireless communication and data transfer between RFID tags and readers. From supermarket anti-theft ...

This is tutorial number 1 from our series of Arduino tutorials and in this part I will talk about blinking an LED using the one already available on the Arduino Uno board or using an external LED to ...
