Week 6

I inspire by Home Security Systems, where for every unusual movement the alarm goes beep beep, so I tried to create a system that gives light when someone gets in the zone of the sensor. (like a singer stage)

Software

Materials

Designing (Tinker CAD)

1- install all materials we are going to use 

• Arduino Uno.

• jumpers.

• USB cable.

• Green LED.

• Resistor.

• breadboard.

• ultrasonic sensor.

2- Connect all components on the breadboard (Parallel).

3- start the  STIMULATION .feature to make sure every component is working.

Coding by blocks in (Tinker CAD)

1- from variables create  a new block named it with Ultrasonic_sensor, then i choosed set Ultrasonic_sensor to.

circuit after connecting it

// C++ code

//

int ultrasonic_sensor = 0;

long readUltrasonicDistance(int triggerPin, int echoPin)

{

  pinMode(triggerPin, OUTPUT);  // Clear the trigger

  digitalWrite(triggerPin, LOW);

  delayMicroseconds(2);

  // Sets the trigger pin to HIGH state for 10 microseconds

  digitalWrite(triggerPin, HIGH);

  delayMicroseconds(10);

  digitalWrite(triggerPin, LOW);

  pinMode(echoPin, INPUT);

  // Reads the echo pin, and returns the sound wave travel time in microseconds

  return pulseIn(echoPin, HIGH);

}

void setup()

{

  Serial.begin(9600);

  pinMode(11, OUTPUT);

}

void loop()

{

  ultrasonic_sensor = 0.01723 * readUltrasonicDistance(13, 12);

  Serial.println("hello world");

  if (ultrasonic_sensor < 10) {

    digitalWrite(11, HIGH);

  } else {

    digitalWrite(11, LOW);

  }

  delay(10); // Delay a little bit to improve simulation performance

}

I googled it, so I knew that I should click on the sensor to make the action (if condition i made on the code).

I Learned how to design a circuit and code it with tinker cad to know how to design & code electrical circuits by using tinker cad, it is going to help me to design & code my final project.
