Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi.

Overview This project demonstrates real-time Bluetooth communication between two Arduinos, leveraging an ultrasonic sensor and a buzzer to detect obstacles and provide audible warnings. Designed as a ...

Introduction In this project we have created a car which is controlled via Bluetooth using a Smartphone. This project helps us to understand the working of Bluetooth module and using it with motors ...

Creating a Bluetooth-controlled device with an Arduino Uno and an HC-05 Bluetooth module enables control of lights or even relays to manage AC appliances wirelessly using an Android smartphone.

So, to address these problems we will make an inexpensive voice-controlled home automation system using easy to find components such as Arduino Nano, HC-05 Bluetooth module and relay driver board. The ...

Arduino is one of those boards that has become synonymous with hacking and making. Since its introduction in 2005, over 700,000 official Arduino boards have been sold, along with untold millions of… ...

Getting Arduino-powered devices to talk to each other over long distances is going to get cheaper and easier if this Kickstarter project flies. Flutter is a wireless development platform for ...
