An Arduino library for I²C GPIO-expander with sample code. To operate the port for input, the IO pins can be configured bit by bit. The config bit for output is 0 and input is 1. When the bit 0 to 3 ...

This repository contains the source code of the Arduino Sketch preprocessor. The main purpose of this tool is to parse an Arduino Sketch (usually made with the Arduino IDE) and convert it into a valid ...

Pins of microcontroller can be used as inputs or as outputs. Output on a microcontroller (Arduino): We use pin of a microcontroller as output , when we want to give command - information to an ...

Detecting motions or movements has always been important in most projects. With the help of the PIR Sensor it has become very easy to detect human/animal movements. In this project we will learn how ...

This project uses the Arduino Uno PWM output to realize a fully isolated analog output with a range of 0..5 V or more. The use of an averaged PWM signal is not comparable with a real DAC, but it has ...

Spread the love“`html Connecting sensors to Arduino opens up a vast array of possibilities for hobbyists and professionals alike, transforming ideas into functional prototypes and projects. Whether ...

The purpose of this project is to provide a 4-20 mA output from a PWM signal generated by a microcontroller. One of the more interesting applications of this circuit would be to replace or to realize ...

A sound sensor is a simple, easy-to-use, and low-cost device that is used to detect sound waves traveling through the air. Not only this but it can also measure its intensity and most importantly it ...

An Arduino is an open source platform which is used to build electronic projects. It consists of hardware (physically programmable circuit board or microcontroller) and software or IDE (Integrated ...

We’ll admit it, we’re all spoiled. A few bucks can now buy a computer that would have been the envy of everyone back in the late 1970s or early 1980s. So it’s no surprise that [krallja] was able to ...
