第十六週 課堂作業及回家作業

第16週12/23寫Arduino的部份

用兩個按鈕控制左右移動

int switchStateRed = 0; int switchStateBlue = 0; int switchStateW = 0; int switchStateA = 0; const int ledPin = 13; // led connected to digital pin 13 const int knockSensor = A0; // the piezo is connected to analog pin 0 const int threshold = 100; int sensorReading = 0; // variable to store the value read from the sensor pin int ledState = LOW;

void setup(){ pinMode(ledPin, OUTPUT); pinMode(4,INPUT); pinMode(5,INPUT); Serial.begin(9600); }

//int a=0,b=0;

void loop(){ sensorReading = analogRead(knockSensor); switchStateW = digitalRead(4); switchStateA = digitalRead(5);

if (sensorReading >= threshold) {

ledState = !ledState;

digitalWrite(ledPin, ledState);

} if(switchStateW == HIGH) {Serial.write('3');} if(switchStateA == HIGH) {Serial.write('4');} delay(33); }
