Arduino Code - Control LED with smartphone App via Bluetooth. The below Arduino example code accepts two commands (“ON” and “OFF”) from Bluetooth Serial Monitor App to turn on/off a built-in LED.

In this instructable I'll show you how to build a custom mobile app to control your Arduino project via Bluetooth. You don't need mobile programming experience to start since a visual App Inventor IDE will be used.

Sep 17, 2020 · You will learn how to create a Bluetooth app that can talk with your Arduino board from scratch and without prior knowledge in Android programming required.

The Reyax BLE Connect app (modified for this demo) handles the Bluetooth communication with the RYB2340 module. When I open the app, it scans for nearby Bluetooth devices and shows the RYB2340 in the list. Tapping it establishes a connection. I customized the app's interface by adding two simple buttons—"Relay On" and "Relay Off"—that send the corresponding text commands to the module when ...

Connect Arduino Uno to Android Via Bluetooth: In this project a serial Bluetooth module is used to create a connection between Arduino Uno and an Android app that I created with MIT App Inventor. Arduino listens for commands to light some LED's or …

Jul 3, 2021 · Establish a BT connection, send command to turn LED on and off and check the status of the LED.

In this Arduino Bluetooth Tutorial we will learn how use the HC-05 module for controlling Arduino via Bluetooth communication. You can watch the following video or read the written tutorial below for more details. For this tutorial I made two example, controlling the Arduino using a smartphone and controlling the Arduino using a laptop or a PC.

Today we will build an Arduino based project which communicates with an app running on a smartphone (Android) via Bluetooth. For simplicity, the goal of the project is to switch a LED connected to the Arduino using the mobile app. We will be using the HC06 Bluetooth module as the major ingredient in this tutorial.

Jul 8, 2018 · Download the Application through link above given. Pair your device with HC 05/06 Bluetooth module1. Turn ON HC 05/06 Bluetooth module2) Scan for available device3) Pair to HC 05/06 by entering default password 1234 OR 0000. After connecting successfully.

May 1, 2020 · So, the main way to do this is by using the bluetooth module and the MIT app inventor too. You have to create an app in order to control the LED using bluetooth. I will demonstrate the app making process. First, the connections are important. There are 6 pins on the bluetooth module. For this project, we will only need to use the middle 4 pins.
