Arduino bluetooth code9/21/2023 ![]() ![]() So actually it reads this: angle,distance. MyPort.bufferUntil('.') // reads the data from the serial port up to the character '.'. MyPort = new Serial(this,"COM8", 9600) // starts the serial communication In this project, there are three main components used an Android Smartphone, Bluetooth transceiver, and an Arduino. Size (1200, 700) // ***CHANGE THIS TO YOUR SCREEN RESOLUTION*** You can watch the following video or read the written tutorial below for more details. When uploading to the Arduino BT, you may need to press the reset button on the board shortly before (or shortly after) clicking upload in the Arduino software. Select Arduino BT from the Tools Board menu of the Arduino environment. This module is widely used and popular You can use any Android/iOS app. In this Arduino Bluetooth Tutorial we will learn how use the HC-05 module for controlling Arduino via Bluetooth communication. Look for a Bluetooth device called ARDUINOBT and the pass code is 12345. ![]() The HC-05 Bluetooth Module is used in this tutorial. The communication between two Arduino via Bluetooth will be presented in another tutorial. Import // imports library for reading the data from the serial port The scope of this tutorial: Arduino exchanges data with the smartphone app. Import rial.* // imports library for serial communication Sets the trigPin on HIGH state for 10 micro secondsĭuration = pulseIn(echoPin, HIGH) // Reads the echoPin, returns the sound wave travel time in microseconds Function for calculating the distance measured by the Ultrasonic sensor rotates the servo motor from 15 to 165 degrees MyServo.attach(12) // Defines on which pin is the servo motor attached Arduino Control DC Motor via Bluetooth In this project we will control a DC motor with a smartphone via bluetooth. PinMode(echoPin, INPUT) // Sets the echoPin as an Input PinMode(trigPin, OUTPUT) // Sets the trigPin as an Output ![]() Servo myServo // Creates a servo object for controlling the servo motor These are very helpful in creating wireless low-energy projects. These add-on cards help you enable the Arduino UNO’s Bluetooth option. HC-05, HC-06, and HM-10 are a few examples. You can connect Arduino to a Bluetooth link using add-on cards. Variables for the duration and the distance How do I connect Bluetooth to Arduino There is no Bluetooth on the Arduino UNO. Defines Tirg and Echo pins of the Ultrasonic Sensor ![]()
