I hope with todays blog, you get a deeper understanding of how to pair Arduino with Bluetooth! On the other hand, if the received character is 1, the LED will light up and the String LED: ON will be sent back. The HC-05 Bluetooth Module is used in this tutorial. In this project, you can upload the new sketch to your Arduino without connecting the Arduino to the computer. There are many application in the Play Store for this purpose which will work with the Arduino code that we wrote. Create a Bluetooth App and control the Arduino - YouTube When you try to pair it, youll be asked for a pin. Using the text() function we print all the text, including the ledStatus string thats coming from the Arduino. So using the first if statement we confine the area of the Turn ON button, so when the button is pressed the character 1 will be sent over the serial port to the Arduino and that will turn on the LED. If so, a one-byte character is read from the device, and if the character is a '1' then LED_BUILTIN is lit, otherwise it gets turned off. Home Automation Using Arduino and Bluetooth Control. In this guide, well show how to connect your Arduino board to a Windows computer using a Bluetooth module. Now the program is ready, so when we will click the run button, the program will automatically activate the Bluetooth communication between the laptop and the Arduino. Since the hc06 bluetooth works on 3.3 v it outputs the data in the form of TTL signal rated at 3.3 v. Where as arduino uno operates on 5 v and its pins output data in the form of TTL signal rated at 5 volt. Copyright 2018 - 2023 ArduinoGetStarted.com. Well that one isnt published yet but it will be in couple of days. Arduino reads data and sends the response back to Bluetooth: Open Android App and pair it with the HC-05 Bluetooth module (similar to the previous example), Arduino receives the data and prints the response to the Serial port. In this final section, well use two Arduino Uno and a pair of Bluetooth modules to get started! You may be wondering; why not the HC-06 or HC-05 Arduino Bluetooth module instead?
