UTILISATION OF SERIAL COMMUNICATION IN ARDUINOHELLO!I am
Osisiogu, UkachiI am here to talk to you about the utilisation of
the serial communication protocol in Arduino. You can e-mail me @

Do you know that?Embedded electronics are the most commonly used
deviced in the world.The world isn't run by weapons anymore, or
energy, or money. It's run by little ones and zeroes, little bits
of data. It's all just electrons. SneakersWhat to expectAn Overview

Serial Communication: Serial communication can be defined as the
form of information exchange in which the individual bits that
compromise the information in the form of bytes or character travel
one after the other through a single channel.
An Overview on Serial CommunicationAn Overview on the
Classifications of Serial CommunicationSerial
CommunicationSynchronousAsynchronousSynchronous Serial
CommunicationIn the synchronous mode, the transmitter and receiver
share a common clockThe transmitter typically provides the clock as
a separate signal in addition to the serial
dataTransmitterReceiverDataClockThe ReceiverExtracts the data using
the clock provided by the transmitter
Converts the serial data back to the parallel formThe
TransmitterShifts the data onto the serial line using its own
clockProvides the clock as a separate signalNo start, stop, or
parity bits added to data

CommunicationWith asynchronous communication, the transmitter and
receiver do not share a common clockTransmitterReceiver+1 byte-wide
DataData1 byte-wide DataThe Receiver
Extracts the data using its own clock
Converts the serial data back to the parallel form after
stripping off the start, stop and parity bitsThe Transmitter
Shifts the parallel data onto the serial line using its own
clock
Also adds the start, stop and parity check bitsAdd: Start, Stop,
Parity BitsRemove: Start, Stop, Parity BitsAsynchronous Serial
CommunicationStart bitindicates the beginning of the data word
Stop bitindicates the end of the data word
Parity bitadded for error detection (optional)
Data bitsthe actual data to be transmitted
Baud ratethe bit rate of the serial port
Throughputactual data transmitted per sec (total bits
transmittedoverhead)Example: 115200 baud = 115200 bits/secIf using
8-bit data, 1 start, 1 stop, and no parity bits, the effective
throughput is: 115200 * 8 / 10 = 92160 bits/sec

ConclusionArduinoThis is a programmable circuit board, and also
an IDE.Serial CommunicationThis is a method of communication
between two devices.Types of Serial
CommunicationSynchronousAsynchronousArduino + Serial
CommunicationThis combination gives Engineers the ability to create
better and more efficient embedded electronicsBottom Line
(Story):The better devices can communicate with each other,
Engineers can be able to create better systems.Let us review some
conceptsThank you for listeningAny questions?
