4. EMBEDDED PROGRAMMING

Sunday 21/07/2024 - Thursday 25/07/2024

1. The microcontroller I used is called the Arduino Nano. I connected it to the laptop and used it.

2. Here is the first step for installing it on Arduino. It may already be installed and just need searching.

3. This is how you find an example code to start with. You can find the code I used here.

4. This is the code for delaying 1 second repeatedly. You can see it in the GIF below.

// 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
}

1. This is the code for delaying 3 seconds and then 0.5 seconds.

// 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(3000);                      // wait for a second
  digitalWrite(LED_BUILTIN, LOW);   // turn the LED off by making the voltage LOW
  delay(500);                      // wait for a second
}

1. There are three challenges we need to complete. I only completed one, which is the Morse code challenge.

2. I completed the challenge where I wrote my name using Morse code. You can find it in the video.

The Code I used to write my name

// 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(2000);                      // 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(2000);                      // 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(1000);                      // 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(1000);                      // wait for a second
  digitalWrite(LED_BUILTIN, LOW);   // turn the LED off by making the voltage LOW
  delay(3000);       // wait for a second

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

  //H

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