Ausgangslage

• Ereignisse haben Audio-Effekte
  • Bumber, Flips, etc.

Bedingungen

• sinvolle Datentypen verwenden

Aufbau

• Seeeduino V4.2
  • als Arduino UNO programmieren
  • nicht als "Seeeduino V4.2"
• Input
  • Wii Nunchuck - I2C Two-Wire Peripheral Interface
  • RTC - I2C Two-Wire Peripheral Interface
• Output
  • Speaker für die Audio-Effekte
    als digiteler Output #define SPEAKER 3 ansteuerbar
  • Led - D8

Handlungsziele

Code Sample

#define SPEAKER 3

int BassTab[] = {1911, 1702, 1516, 1431, 1275, 1136, 1012}; // bass 1~7

void setup() {
  pinMode(SPEAKER, OUTPUT);
  digitalWrite(SPEAKER, LOW);
}

void loop() {
  for (int note_index = 0; note_index < 7; note_index++) {
    sound(note_index);
    delay(50);
  }
}

void sound(uint8_t note_index) {
  for (int i = 0; i < 100; i++) {
    digitalWrite(SPEAKER, HIGH);
    delayMicroseconds(BassTab[note_index]);
    digitalWrite(SPEAKER, LOW);
    delayMicroseconds(BassTab[note_index]);
  }
}

Code Sample RTC

#include <Wire.h>
#include "DS1307.h"

DS1307 clock;                   //define a object of DS1307 class
void setup() {
  Serial.begin(9600);
  clock.begin();
  clock.fillByYMD(2018, 2, 23); // Feb. 23,2013
  clock.fillByHMS(8, 0, 0);     // 08:00 00"
  clock.fillDayOfWeek(FRI);     // Friday
  clock.setTime();              // write time to the RTC chip
}
void loop() {
  printTime();
  delay(1000);
}
void printTime() {               // Function: Display time on the serial monitor
  clock.getTime();
  Serial.print(clock.hour, DEC);
  Serial.print(":");
  Serial.print(clock.minute, DEC);
  Serial.print(":");
  Serial.print(clock.second, DEC);
  Serial.print("	");
  Serial.print(clock.month, DEC);
  Serial.print("/");
  Serial.print(clock.dayOfMonth, DEC);
  Serial.print("/");
  Serial.print(clock.year + 2000, DEC);
  Serial.print(" ");
  Serial.print(clock.dayOfMonth);
