The Arduino Code There are just two default functions in Arduino: void setup and void loop. void setup is where you tell the Arduino board about the common setup just like whether a digital pin will ...

Arduino is both software and hardware. Right there, you can control your design (hardware) through the code (software). So, it's one of the reasons also that Arduino is used extensively in prototyping ...

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 ...

Next is a project example, where the Arduino is instructed to do something based on a correct key (secret number) being entered into the keypad, probably the most demanded application of the keypad.

The Arduino IDE is used to write the program that will interact with your Arduino and the devices connected to it. In the Arduino world, such a program is called a sketch, which has its origin in its ...

This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute (RPM). You don’t need much… ...
