Various types of serial communication can be employed and are designated as Simplex, Half Duplex, and Full Duplex They are also referred to as the sender and receiver. In order to implement serial communication, a source and destination are required. Conversely, binary zero is denoted with a logic LOW or zero volts. The binary digit one is represented by five volts or a HIGH logic. This function is included in the loop to process the data obtained from the mobile.įor details regarding other functions, kindly refer to:įor more information regarding the HC-05 Bluetooth Module visit:ĭabble app for iOS devices supports only Bluetooth Low Energy, therefore you need to use BLE module HM-10 on your hardware while working with iOS devices.Binary pulses are used to transmit data in serial data transmission. To refresh the data that the device gets from the Dabble app, you have to use the following line of code: For evive, we normally get 115200 baud rate modules and for other boards Baud_Rate is set to 9600. Here Baud_Rate is the baud rate set for the Bluetooth module. In the serial port context, "9600 baud" means that the serial port is capable of transferring a maximum of 9600 bits per second. Baud rate is commonly used when discussing electronics that use serial communication. The baud rate is the rate at which information is transferred in a communication channel. To enable Bluetooth communication, you have to initialize serial communication using the following code: There are unique define terms(macro) made for each module.įor example, to use the Gamepad module in the Arduino program, you have to define the following header:

Motor A connects to terminals 1 and 2 while Motor B connects to terminals 3 and 4.Īfter selecting the option 'Add.ZIP Library' select the zip file from your computer to import.Ĭertain macros names depending upon which module you want to use need to be defined. This is very significant especially when using an Arduino board where the 5V power source is simply not enough for two DC motors. The other benefit of using an H-bridge is that we can provide a separate power supply to the motors.
The L298N motor controller follows the H-bridge configuration, which is handy when controlling the direction of rotation of a DC motor.

The H-Bridge Motor Drivers L298N is used to drive DC motors as they require much more current that the arduino can provide.

Used to control the Key/Enable pin to toggle between Data and command ModeĪs soon as the module is powered you should be able to discover the Bluetooth device as “HC-05” then connect with it using the default password 1234 and start communicating with it.Ĭomponent 2 : L298N H-Bridge Motor Driver Repeated Blinking: Waiting for connection in Data Modeīlink twice in 1 sec: Connection successful in Data Mode The state pin is connected to on board LED, it can be used as a feedback to check if Bluetooth is working properly.īlink once in 2 sec: Module is in the Command Mode
Every serial data given to this pin will be broadcasted via Bluetooth Everything received via Bluetooth will be given out by this pin as serial data. Powers the module (connected to +5V Supply voltage) The HC-05 has two operating modes, one is the Data mode in which it can send and receive data from other Bluetooth devices and the other is the AT Command mode where the default device settings can be changed. This pin is used to toggle between Data Mode (set low) and AT command mode (set high).
