Arduino Programming

Hello.

Today I will be sharing about my experience learning more about the arduino uno board.

HOW I PROGRAMMED THE BOARD FOR OUTPUT CONNECTIONS

I learned how to program the board using the tinkercad. Tinkercad makes it so much easier to code as it generates the code from the actions that we were to piece together.

We were tasked to connect a potentiometer to the board and measure its signal in the serial monitor in arduino IDE

I pieced together how I want the components to be connected in the space provided

Then I pieced together the actions that I wanted my product to do using the different "action bubbles"

From there, this will translate into a code which is compatible and can be used in the arduino IDE app.

To verify that this is true, I transferred the code the actual maker uno board. With the serial monitor display in arduino uno IDE opened.

the code is as follows:

// C++ code

int sensorValue = 0;

void setup()

{

pinMode(A0, INPUT);

pinMode(LED_BUILTIN, OUTPUT);

Serial.begin(9600);

}

void loop()

{

// read the value from the sensor

sensorValue = analogRead(A0);

// turn LED on

digitalWrite(LED_BUILTIN, HIGH);

// pause the program for <sensorValue> milliseconds

delay(sensorValue); // Wait for sensorValue millisecond(s)

// turn the LED off

digitalWrite(LED_BUILTIN, LOW);

// pause the program for <sensorvalue> milliseconds

delay(sensorValue); // Wait for sensorValue millisecond(s)

// read the input on analog pin 0:

sensorValue = analogRead(A0);

// print out the value you read:

Serial.print("sensor:");

Serial.println(sensorValue);

}

The end result should be something like this:

Next, we were tasked to connect a light dependent resistor to the maker uno board. I basically replaced the potentiometer with the LDR and used the same code.

I simulated the whole code using the real maker uno board.

Next, we were tasked to learn how to use output connections.

First we had to connect 3 LED lights to make a traffic light. I arranged how I wanted all my components to look like :

I wanted my LED lights to blink alternately with a delay of 1 second. First, I pieced the action bubbles together, and from there it helped me translate it into a code.

The code that came up is:

// C++ code

void setup()

{

pinMode(13, OUTPUT);

pinMode(9, OUTPUT);

pinMode(6, OUTPUT);

}

void loop()

{

// turn led at pin 13 on

digitalWrite(13, HIGH);
