I am discuss most popular & intersecting gadget which name is arudion,this is one type of embeded system another I am called as a mini computer because approximately all computer component have present here but not a computer because many reason are show,first reason is a embedded system have a 16 bit microcontroller where a computer have a 32-128 bit microprocessor,second reason is a embedded system at a time exit one work but a microprocessor at a time working multiple task
Purpose of many project & industrial automation huge amount of use this machine
Let us discuss working principle of Arudino,a Arudino have 14 digital pin & one usb port,this usb port are use prgrammible this arudino & this pins are coonceted many type sensor and actuator ,arudino sense the environment al help of sensor then is control the actuator,The 14 digital input/output pins can be used as input or output pins by using pinMode(), digitalRead() and digitalWrite() functions in arduino programming. Each pin operate at 5V and can provide or receive a maximum of 40mA current, and has an internal pull-up resistor of 20-50 KOhms which are disconnected by default. Out of these 14 pins, some pins have specific functions as listed below:
Serial Pins 0 (Rx) and 1 (Tx): Rx and Tx pins are used to receive and transmit TTL serial data. They are connected with the corresponding ATmega328P USB to TTL serial chip.
External Interrupt Pins 2 and 3: These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value.
PWM Pins 3, 5, 6, 9 and 11: These pins provide an 8-bit PWM output by using analogWrite() function.
SPI Pins 10 (SS), 11 (MOSI), 12 (MISO) and 13 (SCK): These pins are used for SPI communication.
In-built LED Pin 13: This pin is connected with an built-in LED, when pin 13 is HIGH – LED is on and when pin 13 is LOW, its off.
Along with 14 Digital pins, there are 6 analog input pins, each of which provide 10 bits of resolution, i.e. 1024 different values. They measure from 0 to 5 volts but this limit can be increased by using AREF pin with analog Reference() function.
Analog pin 4 (SDA) and pin 5 (SCA) also used for TWI communication using Wire library.
Arduino Uno has a couple of other pins as explained below:
AREF: Used to provide reference voltage for analog inputs with analogReference() function.
Reset Pin: Making this pin LOW, resets the microcontroller.
