Maker Spacer

 October 26, 2026

This is my very first time learning and working with a UNO R3 kit. I am starting with the basic blink code. I changed the delay (1000) to delay (500).

/*
  Blink

  Turns an LED on for one second, then off for one second, repeatedly.
 */
 
// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 12;

 // the setup routine runs once when you press reset:
void setup() {                
  // initialize the digital pin as an output.
  pinMode(led, OUTPUT);    
}

// the loop routine runs over and over again forever:
void loop() {
  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(500);               // wait for a second
  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
  delay(500);               // wait for a second
}

Week 2 Maker spacer challenge

 1. Explanation of the project:  The purpose of this week’s challenge is to use the potentiometer as a means to control the blinking of the LED light.   As the potentiometer is turned, the blinking speeds up or slows down.   2. The following is the code that was used The following is the code that was used.  /* SparkFun Inventor's Kit Example sketch 02   POTENTIOMETER void setup() // this function runs once when the sketch starts up {   // We'll be using pin 13 to light a LED, so we must configure it   // as an output.     // Because we already created a variable called ledPin, and   // set it equal to 13, we can use "ledPin" in place of "13".   // This makes the sketch easier to follow.     pinMode(ledPin, OUTPUT); void loop() // this function runs repeatedly after setup() finishes {   // First we'll declare another integer variable   // to store the value of the pote...

 The purpose of the project is to mimic the random role of a dice.  The button activates the LED lights and it randomly stops to mimic the roll of the dice.   I used two codes to mimic a dice. The first code had the LED lights constantly flashing.   This code worked correctly because the LED lights would flash and stop like a dice.  The following are pictures of the boards.   This project was more difficult because I had issues wiring the boards to make it connect and run properly. It took me several tries to get the connections right. I could not figure out how to place the middle LED, so I left it off.  Another difficulty was the LED lights that did not turn off. For some reason, some of the LED lights remained on, but would flash.   As for the code, it took several tries to get the correct code.  One code had the lights constantly flashing. Then, after some modifications, the code allowed me to use the dice as a random ...
