so you are a final year student and you have no idea how to get the components for your project... from sensors to modules, processors...just send us your list...we've got your back...it's soooooo pocket friendly you won't feel the weight... hub360?....everyone's happy THINK+CREATE+REPEAT

REMOTE CONTROL

REMEMBER WHAT IT WAS LIKE WHEN ALL WE HAD WERE BLACK AND WHITE TELEVISION SETS? AND THEN CAME THE BIG BANG: COLOURED SCREENS!!! WITH BETTER VISUAL DISPLAYS, AND THE COMFORT OF CONTROLLING IT FROM YOUR SEAT WITH THE REMOTE CONTROL. 

 BUT HAVE YOU EVER WONDERED HOW THIS REMOTE CONTROL WORKS?

HAS IT EVER OCCURRED TO YOU THAT YOU CAN HAVE YOUR OWN HOME-MADE REMOTE CONTROLLED DEVICE?

THIS PROJECT TRIES TO ANSWER SOME OF THESE

SO HOW DOES IT WORK?
THE SIMPLE LOGIC IS COMMUNICATION BETWEEN TWO DEVICES, A TRANSMITTER AND A RECEIVER, AND IN THIS CASE, THE REMOTE AND SENSOR RESPECTIVELY VIA INFRA-RED.

WHAT DO WE NEED TO MAKE THIS DREAM A REALITY?

• ARDUINO BOARD
• BREADBOARD
• LEDs (RED, YELLOW AND GREEN)
• 220 OHM RESISTORS X3 (ONE FOR EACH LED)
• TSOP 1838 SENSOR
• REMOTE CONTROL
• JUMPER WIRES

     PLEASE NOTE

• YOU HAVE TO MAKE THE FOLLOWING CONNECTIONS
      
      VCC TO 5V OF THE ARDUINO
      GND TO GND OF THE ARDUINO
      OUT TO PIN 9 OF THE ARDUINO
   
• FOR THIS TOPIC, WE HAVE DECIDED TO USE A SIMPLE SYSTEM YOU SHOULD BE QUITE FAMILIAR WITH NOW

SEE WHAT THE TSOP 1838 LOOKS LIKE

AND THE REMOTE CONTROL

 

WHAT ABOUT THE CODES?

 #include <IRremote.h>
int receiver = 9;
int led1 = 4;
int led2 = 5;
int led3 = 6;
IRrecv irrecv(receiver);
decode_results results;
void setup()
{
  irrecv.enableIRIn();
  pinMode(led1,OUTPUT);
  pinMode(led2,OUTPUT);
  pinMode(led3,OUTPUT);
}
void loop()
{
  if (irrecv.decode(&results)) {
    long decCode = results.value;
    switch(decCode){
      case 16724175:
digitalWrite(led1,HIGH);
digitalWrite(led3,LOW);
digitalWrite(led2,LOW);
break;
case 16718055:
digitalWrite(led2,HIGH);
digitalWrite(led1,LOW);
digitalWrite(led3,LOW);
break;
case 16743045:
digitalWrite(led3,HIGH);
digitalWrite(led2,LOW);
digitalWrite(led1,LOW);
break;
    }
    irrecv.resume();
  }
}

THE ULTRA SONIC SENSOR

 

THIS IS ONE COOL WAY TO TRY OUT SOMETHING WE'VE ALL BEEN DOING SINCE GRADE ONE...

SO THE BIG QUESTION IS "WHAT IS AN ULTRA-SONIC SENSOR...WHAT DOES IT DO?" 

WELL AMONGST OTHER THINGS, IT CAN BE USED TO MEASURE DISTANCE BETWEEN OBJECTS.IT WORKS BY SENDING A SIGNAL FROM ONE OF THE OUTPUTS, THE TRANSMITTER (SEEN HERE ON THE LEFT, MARKED 'T'), THIS SIGNAL, DEPENDING ON ITS STRENGTH, HITS A SOLID OBJECT AND IS REFLECTED BACK, RECEIVED BY THE OTHER OUTPUT (RECEIVER-'R'), AND THE DISTANCE IS CALCULATED

  

 MATERIALS NEEDED

• ARDUINO BOARD AND CABLE
• BREAD BOARD
• 220 OHM RESISTOR FOR THE LED
• ULTRA-SONIC SENSOR
• JUMPER WIRE 
• LED

 THIS IS THE ULTRA SONIC SENSOR (the pins from left to right are VCC, TRIG, ECHO and GND)

 

NOTE: CONNECT YOUR CIRCUIT AS FOLLOWS

• VCC TO ARDUINO 5V
• GND TO ARDUINO GND
• ECHO TO ARDUINO PIN 7
• TRIG TO ARDUINO PIN 8
• LED TO ARDUINO PIN 9

 AND THE CODE (QUITE LENGTHY, OOOPS):

int echopin =7;

int trigpin =8;

int led = 9;

int maxdistance = 200;

int mindistance = 0;

long duration, distance;

void setup(){

  Serial.begin(9600);

  pinMode(trigpin,OUTPUT);

  pinMode(echopin,INPUT);

  pinMode(led,OUTPUT);

}

void loop(){

  digitalWrite(trigpin,LOW);

  delayMicroseconds(2);

  digitalWrite(trigpin,HIGH);

  delayMicroseconds(10);

  digitalWrite(trigpin,LOW);

  duration = pulseIn(echopin,HIGH);

  distance = duration/58.2;

if (distance >= maxdistance||distance <= mindistance){

    Serial.println("OUT OF RANGE");

    digitalWrite(led,HIGH);

  }

  else{

    Serial.println(distance);

    digitalWrite(led,LOW);

  }

  delay(50);

}

 SO WHAT DO YOU THINK?

TACT SWITCH

 the tact switch functions like a normal switch that can be used to control a circuit

WHAT WE'LL NEED

• ARDUINO BOARD & CABLE
• BREADBOARD
• TACT SWITCH
• LED
• 10K RESISTOR
• JUMPER WIRE

 THE CODE SHOULD LOOK LIKE THIS

int switch =4; // tact switch connected to analog pin 4
int led = 3;// led connected to pin 3
int x;
void setup(){
  pinMode(switch,INPUT); //set tact as input
  pinMode(led,OUTPUT);  //set led as output
}
void loop(){
  x= digitalRead(switch); //read to know if switch is detected or not
  digitalWrite(led,x);  //ON or OFF an LED according to detection
}

SO WHAT EXACTLY IS A TILT SENSOR...WHAT DOES IT DO?
simply put, it is an electronic device, quite small (about the size of an LED); it acts like an ordinary switch, the switch closes when the sensor is tilted and opens when brought to its original position.

and amongst other things, a tilt sensor can be used to determine angular deviation (from the normal).


SO WHAT COMPONENTS DO WE NEED FOR THIS CONNECTION?

•  ARDUINO BOARD AND CABLE
• BREADBOARD
• TILT SENSOR
• LED
• 220 OHM RESISTOR (FOR THE LED)
• 10K RESISTOR
• JUMPER WIRE

SEE WHAT THE SKETCH LOOKS LIKE

  pinMode(led,OUTPUT);  //set led as output

  digitalWrite(led,x);  //ON or OFF an LED according to detection

THIS IS AWESOME

 so you're watching that sci-fi movie and you say "hey dude, *****wood's at it again with all their studio tricks...HOW THE **** DID A LIGHT COME ON WHEN THIS DUDE WALKED BY?"
well, believe it, it's no trick! 
why? 'cos that's what you are about to see... READY?

    WHAT YOU NEED TO PERFECT YOUR OWN *****WOOD TRICK?

• your arduino board+cable      
•  breadboard
•  10k resistor
•  PIR motion sensor
• jumper wire

   HERE IS THE SKETCH

}
void loop(){
  x= digitalRead(motion); //read to know if motion is detected or not
  digitalWrite(led,x);  //ON or OFF an LED according to detection
}




NOTE: 

• WHEN CONNECTING YOUR COMPONENTS, THE VCC OF THE PIR IS CONNECTED TO 5V PIN ON THE ARDUINO BOARD
• THE GROUND OF THE PIR IS CONNECTED TO THE GROUND PIN OF THE ARDUINO
• THE OUT OF THE PIR IS CONNECTED TO PIN4MOF THE ARDUINO
• THE ANODE (POSITIVE LEG) OF THE LED IS CONNECTED THROUGH A 220OHM RESISTOR TO PIN3 OF THE ARDUINO
• THE CATHODE (NEGATIVE) OF THE LED IS CONNECTED TO THE GROUND OF THE ARDUINO

    

A. LED (ON THE BREAD BOARD) IS OFF DUE TO ABSENCE OF MOVING OBJECT

B. LED (ON THE BREAD BOARD) COMES ON AS IT SENSES MOVING OBJECT

PROJECT 3

hello there. how are you finding our classes? interesting we presume....

have you ever wondered about the possibility of an
AUTOMATIC LIGHTING SYSTEM? the ability to lighten up your home via
a trigger (not a conventional switch)?

ever went out and forgot to turn off those lights? (ooops, more bills)

anyway, for today's class, we will be addressing just that: the ability to
control your lighting system with a light-dependent resistor (LDR)

YEEEEAAAAHHHHHHHHHH!!!!

 "how does it work"? quite simple
 the LDR is sensitive to light and comes on when it senses light, and turns
 off automatically when there is darkness... "THIS IS AWESOME"

 SO WHAT DO WE NEED?
   
    * arduino board+cable
    * breadboard
    * 220 ohm resistor
    * 10k resistor
    * LED
    * light-dependent resistor
    * jumper wire

 HERE'S THE SKETCH

 /* using an ldr to off and ON an led connected to pin 3 of the arduino...

*/
int ldr =0; //ldr connected to analog pin 0
int led = 3;// led connected to pin 3
int x;
void setup(){
  pinMode(ldr,INPUT);
  pinMode(led,OUTPUT);
}
void loop(){
  x= analogRead(ldr); // read ldr and store in varible x
  if(x<100)
  {
    digitalWrite(led,HIGH); // turn on led when ldr is covered
  }
  else if(x>100)
  {
    digitalWrite(led,LOW);//off led when ldr is exposed to light
  }
}

THIS IS WHAT YOUR CONNECTION SHOULD LOOK LIKE

         VOILA!!!

BE SEEING YOU SOON. TILL THEN,
