4. Embedded programming¶

This week I worked on programing a microcontroller. I worked on Arduino IDE.

Using Arduino¶

what is Arduino?¶

“Arduino is an open-source electronics 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 microcontroller on the board. To do so you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing.”

Arduino MKR wifi 1010: The MKR WiFi 1010 is a miniature sized modulecontaining a SAMD21G18A Processor, the NinaW102 Module, a crypto chip (the ATECC508), and a2MByte SPI Flash.

Task1: Blink.¶

First start with downloading the app for Arduino from their official website.

looking for examples:

It required downloading the board to the Arduino.

/*
  Blink

  Turns an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
  it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
  the correct LED pin independent of which board is used.
  If you want to know what pin the on-board LED is connected to on your Arduino
  model, check the Technical Specs of your board at:

  This example code is in the public domain.

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}

Task2: Random Delay.¶

I tried to set random function using the code below

void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
int A=random(500,5000);
Serial.println(A);
int B=random(500,5000);

for(int j=0; j<10; j++){
  digitalWrite(LED_BUILTIN,HIGH);
  delay(A);
   digitalWrite(LED_BUILTIN,LOW);
  delay(B);
}
}

Task3: Morse code.¶

First, I wrote my name in morse code by using this website to make the LED light on/off.

0.5 second light on for dot
1.5 second light on for dash
0.5 second light off for space between letters
2.5 light off for the end of the word
I wrote my code in this way :

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {

  //Y
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1500);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(500);                       // wait for a second

    digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(500);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(500);                       // wait for a second

    digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1500);                       // wait for a second

  delay(500);                       // wait for a second

  delay(500);                       // wait for a second

      digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
