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 ...

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 ...

If you're looking to make yourself somewhat more productive on this lazy weekend, and you've got an Arduino or two collecting dust, we've got just the thing to add line after line to your dwindling to ...

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 ...

In this experiment we are going to use a element called photoresistor. This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light ...
