[DAY 1] Get to know, connect and install

Test material

Necessary materials:

• Computer
• Arduino IDE
• Arduino UNO
• 3 LEDS connected in serie
• Cables to Arduino

Steps:

1. Install Arduino IDE
   1. Go to https://www.arduino.cc/en/software
2. Open Arduino IDE, go to File > Examples > Basics > Blink
3. Press Upload. Check that the LED is blinking
4. Install Neopixel Library. Go to Library Manager > Search for Adafruit Neopixel > Install
5. Test Neopixel test. Go to File > Examples > Neopixel > Strandtest
6. Modify NUMPIXELS to be 3
7. Press Upload. Check that the LEDS are green.

#include <Adafruit_NeoPixel.h>

#define PIN        6 

#define NUMPIXELS 3

Adafruit_NeoPixel pixels(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);

void setup() {
  pixels.begin(); // INITIALIZE NeoPixel strip object (REQUIRED)
}

void loop() {
  pixels.clear(); // Set all pixel colors to 'off'

  for(int i=0; i<NUMPIXELS; i++) {
    pixels.setPixelColor(i, pixels.Color(0, 150, 0));
    pixels.show();   // Send the updated pixel colors to the hardware.
    delay(500); // Pause before next pass through loop
  }
}

Ideas for projects

Work for next day: Think what project you want to work in, bring the clothes for next day.

[DAY 2] Program and design

Arduino program structure

#define VARIABLE 123

void setup(){
    // This is a comment
    // Setup is run once
}

void loop(){
    // Loop is running constantly
}

Blink example

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
}

Challenge: How can we make the blink faster?

Neopixel program structure

#include <Adafruit_NeoPixel.h>

#define PIN        6 

#define NUMPIXELS 3

Adafruit_NeoPixel pixels(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);

void setup() {
  pixels.begin(); // INITIALIZE NeoPixel strip object (REQUIRED)
  
  pixels.clear(); 
  pixels.show(); 
}

void loop() {
  pixels.clear(); // Set all pixel colors to 'off'

  pixels.setPixelColor(0, pixels.Color(150, 0, 0));
  pixels.show();
  delay(1000);

  pixels.setPixelColor(1, pixels.Color(0, 150, 0));
  pixels.show();
  delay(1000);

  pixels.setPixelColor(2, pixels.Color(0, 0, 150));
  pixels.show();
  delay(1000);
}

Challenge: How can we display white? How can we make it faster?

Keywords

delay(1000);         // Wait for 1 Sec
delay(5000);         // Wait for 5 Sec
delay(500);         // Wait for 500 Milliseconds

pixels.setPixelColor(0, pixels.Color(0, 0, 0));          // Set pixel number 0 to black
pixels.setPixelColor(1, pixels.Color(255, 0, 0));        // Set pixel number 1 to red
pixels.setPixelColor(2, pixels.Color(0, 255, 0));        // Set pixel number 2 to green
pixels.setPixelColor(0, pixels.Color(0, 0, 255));        // Set pixel number 0 to blue
pixels.setPixelColor(1, pixels.Color(255, 255, 0));      // Set pixel number 1 to yellow

pixels.clear();          // Clean the screen
pixels.show();           // Apply configuration to LEDS

// Repeat 3 times: Put led on color red
for (int i = 0; i < 3; i++) {
  pixels.setPixelColor(i, pixels.Color(255, 0, 0));
  pixels.show();
  delay(100);
}

You can use examples from the library in Examples > Neopixel
