Andino M1平台-使用Arduino IDE開發(13)_Due & Zero only

1. 電路圖:

2. 程式:

void setup() {
  // open a serial connection
  Serial.begin(9600); 
}

void loop() {
  // read the input on A0 at default resolution (10 bits)
  // and send it out the serial connection 
  analogReadResolution(10);
  Serial.print("ADC 10-bit (default) : ");
  Serial.print(analogRead(A0));

  // change the resolution to 12 bits and read A0
  analogReadResolution(12);
  Serial.print(", 12-bit : ");
  Serial.print(analogRead(A0));

  // change the resolution to 16 bits and read A0
  analogReadResolution(16);
  Serial.print(", 16-bit : ");
  Serial.print(analogRead(A0));

  // change the resolution to 8 bits and read A0
  analogReadResolution(8);
  Serial.print(", 8-bit : ");
  Serial.println(analogRead(A0));

  // a little delay to not hog serial monitor
  delay(100);
}
