In embedded systems, the communication means the exchange of data between two microcontrollers in the form of bits. The communication is very well known terminology which involves the exchange of information between two or more mediums.

Simply connect the board to PC and make sure driver is installed for the board and it is detected by PC.Before starting with Serial Communication Protocols, Let’s break the terminology in three parts. For some project, we may require more components.
So for that, we are using only the Arduino UNO board. In this tutorial, we are covering some useful basic functions of arduino. See images below:Ī sensor value with some text is displayed over the pc by the arduino using serial communication. By simply click, the serial monitor pops up. Its very easy to work with serial and serial monitor. A text also be displayed over the pc for some interaction with user and arduino.
RELIABLE SERIAL COMMUNICATION PROTOCOL CODE
Write the code for serial, that will read the sensor value you want to display over the PC using arduino serial monitor.
RELIABLE SERIAL COMMUNICATION PROTOCOL BLUETOOTH
Here we have shown a connection between arduino and bluetooth module. Then simply make cross connection between RX and TX of peripheral to the arduino. For communication, all peripheral should have UART in it. Means a cross connection is required.Īrduino can be connected to any devices like gps, rfid-reader, bluetooth, GSM modem, RF pair and more. The TX of one Arduino goes to RX of Arduino 2 and RX of Arduino 1 to TX of Arduino 2. Arduino 1 and Arduino 2 board want serial communication in between.

How to Make Connections in Serial Communication
How to Interface Bluetooth with Arduino. We have used serial communication in different arduino projects like: This data could be a text or any sensor value. And at the PC side, we have the Arduino IDE running its serial monitor for accepting the data coming from the arduino board. One advantage here is arduino has some on board IC that converts the TTL serial data to USB understandable. If a board doesn’t have USB to TTL IC in it we need to add it separately to perform serial communication with pc. How to Connect Arduino to PC for Serial CommunicationĪrduino PC interface is very easy by writing serial communication program into arduino and by using serial monitor program. Here we have set the arduino to 9600 baud rate. We simply put the desired baud rate we need. In arduino there is a library function, Serial.begin(9600) so we don’t require to calculate the. By calculating the ubrr for a given baud rate and placing this into the programming we get the desired baud rate. AVR microcontroller has a register called UBRR(UART baud rate register). For doing this we need to calculate the common baud rate for both devices and putting this value in programming code on both devices. In data communication some time both hardware are working at different frequencies even though we need to establish the communication between the devices. UART Baud Rateįor a reliable communication both the devices should have a same baud rate. Then stop bit is one(1) indicating receiver that frame is over and be ready for the next frame in the same manner. And then there is a Data of 8-bit length, each goes one bit by one bit. The start of the frame is Zero(0) tells the other UART receiver that some data is about to come. In UART there is a data frame to send the data. A serial device sends information(byte) one bit at a time to the receiver at a certain rate that is called baud rate. 6.3.3 Display value in DEC, HEX, OCT, BIN to Serial MonitorĪny devices that have UART capability can communicate with each other with using the two wires TX and RX. 6.3.2 Send Analog Data to Serial Monitor. 6.3.1 Send Hello World to Serial Monitor. 6.3 Arduino Code for Serial Communication. 5 Bluetooth Serial Connection with Arduino. 4 How to Make Connections in Serial Communication.
