One problem with all those Arduino variants is, that the pins are different between them. Most of the example sketches are written for the Uno, which is the most common variant. And often the pin ...

In this project, I build an Automated Greenhouse system using Arduino UNO which is capable of monitoring and managing plants without human intervention. I work with various sensors like the DHT, LDR, ...

The damages that can be done by fire are devastating. To prevent causalities or damages, it is necessary to detect the fire, so that warnings can be provided and even automatic fire suppression ...

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 ...

Here you will simulate control of a robot rover using an Atmel 328 microprocessor communicating with LabVIEW controls and indicators; the code is created in the Arduino environment. Read about Arduino ...

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 ...

If you buy something using links in our stories, we may earn a commission. Learn more. Last week I explained how to use a motion sensor to trigger an event with an Arduino. The event we triggered was ...

Need to quickly toggle or read some logic signals without the hassle of writing a quick program? [Thor_x86], aka [Eric], built an Arduino sketch that does just that — and he threw in the ability to ...

Arduino Portenta H7 Lite is a cost-down version of Portenta H7 STM32H7 that shaves off a little over $30 of the Arduino Pro board by doing without a wireless module nor USB-C video output and opting ...
