Assignment

1-Group assignment

Measure the power consumption of an output device

2-Individual assignment

Add an output device to a microcontroller board you've designed, and program it to do something

2-Individual assignment:

Add an output device to a microcontroller board you've designed, and program it to do something

For this assignment, I will test my outputs using ARDUINO UNO

The outputs that might be used for my final project are the following:

• Servo Motor
• Stepper Motor
• LCD I2C Screen

PIR Sensor:

I have watched the following youtube video to help me out

And I started to follow the steps as per the below in order to connect my PIR Sensor to the ARDUINO UNO

I found out that the PIR Sensor takes one digital pin from the ARDUINO in additiong to VCC and GND of course

You may look at the connections in the images below

And for the coding part, I have used the one available on the ARDUINO website

as per the below:

 * The Parallax PIR Sensor is an easy to use digital infrared motion sensor module. 
 * (https://www.parallax.com/detail.asp?product_id=555-28027)
 *
 * The sensor's output pin goes to HIGH if motion is present.
 * However, even if motion is present it goes to LOW from time to time, 
 * which might give the impression no motion is present. 
 * This program deals with this issue by ignoring LOW-phases shorter than a given time, 
 * assuming continuous motion is present during these phases.

     if(digitalRead(pirPin) == HIGH){
       digitalWrite(ledPin, HIGH);   //the led visualizes the sensors output pin state

     if(digitalRead(pirPin) == LOW){       
       digitalWrite(ledPin, LOW);  //the led visualizes the sensors output pin state

       if(takeLowTime){
        lowIn = millis();          //save the time of the transition from high to LOW
        takeLowTime = false;       //make sure this is only done at the start of a LOW phase
        }
       //if the sensor is low for more than the given pause, 
       //we assume that no more motion is going to happen
       if(!lockLow && millis() - lowIn > pause){  
           //makes sure this block of code is only executed again after 
           //a new motion sequence has been detected
           lockLow = true;                        
           Serial.print("motion ended at ");      //output
           Serial.print((millis() - pause)/1000);
           Serial.println(" sec");
           delay(50);
           }
       }
  }
 

And I have also tested the one in the youtube video above:

   
                            int val = 0;

void setup() {
  // put your setup code here, to run once:
pinMode(13, OUTPUT);
pinMode(3, INPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
val = digitalRead(3);

if (val == HIGH)
{
  digitalWrite(13, HIGH);
}
if (val == LOW)
{
  digitalWrite(13, LOW);
}
}

The test can be checked in the below video:
