Aug 4, 2020 · now you control your led using a mobile app. If you get an error message like this then remove the txd and rxd pin of the bluetooth module from the Arduino and then upload the code again and connect the pins to its respective places.

Learn how to controls LED via Bluetooth or BLE (Bluetooth Low Engery) using Arduino, how to controls LED via smartphone using HC-05 Bluetooth module or HM-10 Bluetooth module

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.

Mar 23, 2018 · Interface an Android smartphone with an Arduino via Bluetooth to control an LED from your phone.

Remote Controlled LED Using HC-05 Bluetooth, Arduino and Mobile Phone App: If you are looking to connect a BLE (Bluetooth 4.0) module instead of Bluetooth 2.0 module, please see my new tutorial: How to control Arduino with HM-10 (CC2541) BLE module and a mobile app. Technology is progressing at break-neck speed, everyone …

In this article, I will demonstrate how to build an IoT project using Arduino (Arduino UNO) and Bluetooth module HC-05 to control LED lights. In this project, we will use an Android smartphone to send a bluetooth signal to a bluetooth module.

Here is what you need to control Led's with Bluetooth: Arduino; HC-05 Bluetooth module; Solder less breadboard; 3 Led's; 3 220Ω resistors; Wires; Most importantly your phone and a downloaded Bluetooth app(I recommend using the Arduino Bluetooth Controller which offers many different features)
