Servo Motor and Ultrasonic Sensor in Action - Toll Gate Project

Arduino Code:

#include <Servo.h>

int redLed = 13;

int triggerPin = 3;

int echoPin = 4;

int servoPin1 = 7;

int servoPin2 = 10;

int yellowLed = 2;

Servo myServo1;

Servo myServo2;

void setup() {

// put your setup code here, to run once:

Serial.begin(9600);

pinMode(redLed, OUTPUT);

pinMode(yellowLed, OUTPUT);

pinMode(triggerPin, OUTPUT);

pinMode(echoPin, INPUT);

myServo1.attach(servoPin1);

myServo2.attach(servoPin2);

}

void loop() {

// put your main code here, to run repeatedly:

long duration, distance;

digitalWrite(triggerPin, LOW);

delayMicroseconds(2);

digitalWrite(triggerPin, HIGH);

delayMicroseconds(10);

digitalWrite(triggerPin, LOW);

duration = pulseIn(echoPin, HIGH);

distance = (duration/2) / 29.1;

Serial.print("Distance: ");

Serial.println(distance);

if (distance < 20) {

digitalWrite(redLed,LOW);

digitalWrite(yellowLed, HIGH);

myServo1.write(90);

myServo2.write(90);

}

else {

digitalWrite(redLed,HIGH);

digitalWrite(yellowLed, LOW);

myServo1.write(0);

myServo2.write(180);

}

Robotics & Electronics Awareness Bootcamp

Date / Time / Venue

January 21, 2017 - 12.15pm-1.45pm

Ashburn Library

Hay Road, Ashburn, VA

RSVP at: https://goo.gl/forms/dt2aIBHt9suxaBhA2

Vision:

Create awareness and bring an avenue where kids can learn the basics of electronics in order to build robotic and Internet of Things (IoT) gadgets.

Mission:

Make the state of the art (science and technology) available and accessible for the kids with proper education curriculum that is focused on fundamentals. The establishment of a very strong academics, practical lab experience along with awareness will motivate the kids to bring their dreams to reality.

Overview:

Use Arduino and Raspberry Pi Microcontrollers
Programming Techniques (Sketch, Python, Java etc,.)
Introduction to electronics using simulation software
Materials

Core Benefits:

Enrich STEAM (Science, Tech, Engg, Art and Math)
Help to achieve good grades for Tech Ed (Tech Eduction)
Opportunity to touch, feel, use and build IoT
Build Robotics Projects (use of motors, sensors etc.,)
Enrich analytical, tactical and logical skills

Eligible Kids:

Listen and follow guidelines (K2 and Above)

Jan14 Stone Ridge Bootcamp Event Slide Show

Servo Motor and Arduino Basics

Arduino Sketch:

#include <Servo.h>

Servo myServo;

int servoPin = 9;

// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
myServo.attach(servoPin);
}

// the loop routine runs over and over again forever:
void loop() {
//Moving forward in the increments of 45 degrees, upto 180 degree
myServo.write(45);
delay(1000);
myServo.write(90);
delay(1000);
myServo.write(135);
delay(1000);
myServo.write(180);
delay(1000);

//Moving backward in the deccrements of 45 degrees, upto 0 degree
myServo.write(135);
delay(1000);
myServo.write(90);
delay(1000);
myServo.write(45);
delay(1000);
myServo.write(0);
delay(1000);

How to install Arduino IDE?

Introduction to Circuits.io .... an online simulator building circuits ...

Learn programming using Arduino IDE ...

How to use Ultrasonic Sensor?

Arduino Sketch Code is as below:

// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int sig = 7;
int led = 3;

// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
Serial.begin(9600);
pinMode(led, OUTPUT);
}

// the loop routine runs over and over again forever:
void loop() {
pinMode(sig, OUTPUT);
digitalWrite(sig, LOW); // turn the LED on (HIGH is the voltage level)
delayMicroseconds(2); // wait for a second
digitalWrite(sig, HIGH); // turn the LED off by making the voltage LOW
delayMicroseconds(5); // wait for a second
digitalWrite(sig, LOW);

pinMode(sig, INPUT);
long duration = pulseIn(sig, HIGH);
int distance = duration / 74 / 2;

Serial.print("distance ");
Serial.println(distance);

if (distance <50){
tone(8, 1000, 500);
digitalWrite(led, HIGH);
delay(100);
}

digitalWrite(led, LOW);
delay(100);

}

Note: I am using circuits.io for simulating the task,
