Sending data between an Arduino or compatible board and a Bluetooth-equipped device such as an Android smartphone or tablet is very easy thanks to the inexpensive HC-06 Bluetooth modules you may have seen on the market. They are also.

This tutorial will explain how to setup communications between an Arduino and a Bluetooth device running serial terminal software - in this case an Android smartphone. Please note that the Bluetooth module used in this tutorial is not compatible with iOS devices - instead, you will need a Bluetooth LE (Low Energy) module or an Arduino-compatible with onboard BLE such as the. So let's get started. Our end goal is to control a digital output pin on the Arduino by sending text commands from the smartphone, and also sending text from the Arduino back to the smartphone. Tap the in the list, and you will then be asked for the PIN - it is 1234. Finally, open your terminal app on the smartphone, and select 'Connect a device' from the app menu.

Select the HC-06 option and then wait a moment. The LED on the Bluetooth module should stay on and the app will show 'connected: HC-06'. Now send the number 1 through the terminal and the onboard LED on the Arduino should turn on. Send 2 and it should turn off. The Arduino will also respond and send the status back to the app, for example see the image in this step.

It supports wireless serial communication over bluetooth. The Arduino BT can be programmed with the Arduino software. For details, see the. You don’t have to use these, though. Use whatever sensors are appropriate to your final application.

For a quick demonstration of the entire process, watch the video in this step.

Serial Communication is a protocol in an embedded system for communication between the microcontroller based devices like arduino and raspberry pie to other peripheral devices supporting the serial communication protocol. This protocol is also known as UART or USART(universal asynchronous receiver/transmitter). It follows the UART protocol It is very popular because it uses only two wire for communication the digital pin 0(RX) and digital pin 1(TX). Wondershare mobiletrans activation.

When using serial communication these two pins can’t be used as the digital pins.
