Hola a todos.
Intento hacer un proyecto usando leds ws2812b. Soy nuevo en usar arduino y casi no se de programación.
Lo que intento hacer es que conectando un switch a un arduino nano que no se encienda ningun led hasta pulsar el switch inicie un efecto y no termine y que al pulsarlo inicie otro diferente y así sucesivamente (unos 4 o 6 efectos diferentes) y que al final después de haber pulsado el switch para los diferentes efectos los leds queden apagados.
¿alguien que me pueda orientar con un ejemplo de como realizar el codigo?
Aqui tengo un codigo que encontre en internet y le agregue 4 efectos pero no logro realizar lo que deseo:
#include <Adafruit_NeoPixel.h>
#define BUTTON_PIN A1 // Digital IO pin connected to the button. This will be
// driven with a pull-up resistor so the switch should
// pull the pin to ground momentarily. On a high -> low
// transition the button press logic will execute.
#define PIXEL_PIN 9 // Digital IO pin connected to the NeoPixels.
#define PIXEL_COUNT 8
#define BRIGHTNESS 100
// Parameter 1 = number of pixels in strip
// Parameter 2 = pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
// NEO_RGB Pixels are wired for RGB bitstream
// NEO_GRB Pixels are wired for GRB bitstream, correct if colors are swapped upon testing
// NEO_RGBW Pixels are wired for RGBW bistream
// NEO_KHZ400 400 KHz bitstream (e.g. FLORA pixels)
// NEO_KHZ800 800 KHz bitstream (e.g. High Density LED strip), correct for neopixel stick
Adafruit_NeoPixel strip = Adafruit_NeoPixel(PIXEL_COUNT, PIXEL_PIN, NEO_GRB + NEO_KHZ800);
bool oldState = BUTTON_PIN,off;
int showType = BUTTON_PIN,on;
void setup() {
pinMode(BUTTON_PIN, INPUT_PULLUP);
strip.setBrightness(BRIGHTNESS);
strip.begin();
strip.show(); // Initialize all pixels to 'off'
}
void loop() {
// Get current button state.
bool newState = digitalRead(BUTTON_PIN);
// Check if state changed from high to low (button press).
if (newState == HIGH && oldState == LOW) {
// Short delay to debounce button.
delay(100);
// Check if button is still low after debounce.
newState = digitalRead(BUTTON_PIN);
if (newState == HIGH) {
showType++;
if (showType > 4)
showType=0;
startShow(showType);
}
}
// Set the last button state to the old state.
oldState = newState;
}
