 Simple Mini Projects using “ARDUINO”

 What is Arduino ?

Arduino is the name of the carporation that manufactures the varies microcontrollers in which Arduino uno is the one of the Microcontroller, which is commonly used in the Embedded Applications, Embedded System is nothing but a system is designed to perform the specific task, which is the combination of software, hardware & Firmware.

 

Microcontroller

Microcontroller is a  heart of the Embedded System, It is a mini computer consists of CPU, CU, I/O, Memory, Power Supply etc.

 

 

 Basic Building Block of the Microcontroller

 

How Microcontroller Works?

The main part of Microcontroller is CPU called Brain of the Microcontroller consists of ALU & CU which helps in performing arithmetic or logical operations based on the set of instruction given to the microcontroller and those instructions or data is  stored in the memory such that specific works is done. In order to perform task on the microcontroller input must be in the form of electric signal, so to analyze any physical parameter it is essential to convert it into electric form & also when we need to show some output from the microcontroller it is even important to convert the output signal coming from the microcontroller because it is in the form of electric signal we human being can’t understand the electric signal it again converted into the physically from of signal such as Vibration, light, motion ect. Which can be done with help of the transducers.

 

Transducer

Since our Microcontroller can understand only the electric signals it is essential to convert the physical form of the signal into electric signal such that expected operation can be performed on the signal.

transducer converts one from of energy into other form of energy, for example electric energy into physical form of the energy that is Actuator and vice-versa that is Sensor.

 Distance Measuring Using Ultrasonic Sensor

 

Interfacing of Ultrasonic Sensor with Arduino

// Distsnce Measuring using the ultrasonic Sensor

#define tri 2

#define eco 3

float duration;

float distance;

void setup(){

  Serial.begin(9600);

  pinMode(tri,OUTPUT);

  pinMode(eco,INPUT);

}

 

void loop(){

  digitalWrite(tri,LOW);

  delayMicroseconds(2);

  digitalWrite(tri,HIGH);

  delayMicroseconds(10);

  duration=pulseIn(eco,HIGH);

  distance=(duration*0.034)/2;

  Serial.print("Distance =");

  Serial.print(distance);

  Serial.print("cm\n");

}
