To build this project, all you need is three main components: an Arduino Uno, a 16x2 LCD, and a push button. You can connect everything to a breadboard to keep it simple.

A n Arduino is a microcontroller — a single board designed to control something and perform a specific task. Unlike a ...

This DIY gas leakage detector is designed for educational and basic monitoring purposes. For critical safety applications, ...

Both the Arduino Nano and Uno can be powered via their integrated USB connectors. This automatically supplies regulated 5V power to the board, allowing you to use any USB-supported power source ...

Nice method and analysis. The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.

Each sensor can be communicated with using I2C from analog pins 4 and 5 on the Arduino Uno. We powered the sensor stick using the 5 volts out available on the Arduino Uno.

Although it seems many have moved on to 32-bit MCUs these days for projects, there is still a lot of fun to be had in the 8-bit AVR world, as [Scott Porter] demonstrates with a recent Arduino Uno ...

It’s a fairly simple project, too: just hook an Arduino Uno up to a motion sensor and an electronic switch called a relay, then plug in your fan, and you’re good to go.

This article describes the construction of a simple Arduino RFID Access control DIY (Do It Yourself) Project using Arduino UNO and a RFID reader module (EM-18) to control an LED and a Relay. Circuit ...
