Arduino UNO Board Projects Code
In this post i will show the code of various school based and college and engineering and techfast based code and project with Youtube Video.
Most of the example code are tested and run on arduino
Introduction of Arduino:-
Arduino is an open-source prototyping platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the micro controller on the board. It is like the brain of a project.

Project 1:-
RGB Colour Intensity Reading of Any Object
Sensor Name:- TCS3200
Tis post have the code for reading the color intensity RGB color of any object.
To demonstrate this i use a color sensor and ardunio uno board
Pin Details:-
Pin 4 Ardunio uno board is connect to RED line of Sensor
Pin 5 Ardunio uno board is connect to GREEN line of SensorPin 6 Ardunio uno board is connect to BLUE line of Sensor
#define Red 4
#define Green 5
#define Blue 6
char inputs [20];
char oldInputs [20];
void setup()
{
Serial.begin(9600);
}
void getInputs()
{
sprintf(inputs,"SS:%03X:%03X:03X",analogRead(Red),analogRead(Green),analogRead(Blue));
}
void loop()
{
getInputs();
if(strcmp(inputs,oldInputs)!=0)
{
strcpy(oldInputs,inputs);
Serial.println(inputs);
}
if(Serial.available())
{
int ind=0;
char buff[5];
while(Serial.available())
{
unsigned char c=Serial.read();
buff[ind]=c;
if(ind++>4)
break;
}
}
}

Project 2:-
Ultrasonic RADAR Demo Project
Ultrasonic Sensor:
An ultrasonic sensor is an instrument that measures the distance to an object using ultrasonic sound waves.
An ultrasonic sensor uses a transducer to send and receive ultrasonic pulses that relay back information about an object’s proximity.
High-frequency sound waves reflect from boundaries to produce distinct echo patterns
Processing Application :
Processing is a flexible software sketchbook and a language for learning how to code within the context of the visual arts. Since 2001, Processing has promoted software literacy within the visual arts and visual literacy within technology. There are tens of thousands of students, artists, designers, researchers, and hobbyists who use Processing for learning and prototyping.
#define echoPin 7
#define trigPin 8
#define LEDPin 13
int maximumRange = 200; // Maximum range needed
int minimumRange = 0; // Minimum range needed
long duration, distance; // Duration used to calculate distance
void setup() {
Serial.begin (9600);

pinMode(echoPin, INPUT);
pinMode(LEDPin, OUTPUT); // Use LED indicator (if required)
}

/* The following trigPin/echoPin cycle is used to determine the
distance of the nearest object by bouncing soundwaves off of it. */

//Calculate the distance (in cm) based on the speed of sound.
distance = duration/58.2;
if (distance >= maximumRange || distance <= minimumRange){
/* Send a negative number to computer and Turn LED ON
to indicate "out of range" */
Serial.println("-1");
digitalWrite(LEDPin, HIGH);
}
else {
/* Send the distance to the computer using Serial protocol, and
turn LED OFF to indicate successful reading. */

//Delay 50ms before next reading.
