Project 03 Love-O-Meter 溫度測試亮燈

隨著溫度的上升，讓燈泡亮起來

============================================================

const int sensorPin = A0; const float baselineTemp = 20.2; void setup(){ Serial. begin(9600); for(int pinNumber = 2; pinNumber<5; pinNumber++){ pinMode(pinNumber, OUTPUT); digitalWrite(pinNumber, LOW); } }

void loop(){ int sensorVal = analogRead(sensorPin); Serial.print("Sensor Value: "); Serial.print(sensorVal); float voltage = (sensorVal/1024.0) * 5.0; Serial.print(", Volts:"); Serial.print(voltage); Serial.print(", degrees C:"); float temperature = (voltage - .5)*100; Serial.println(temperature); if(temperature < baselineTemp){ digitalWrite(2, LOW); digitalWrite(3, LOW); digitalWrite(4, LOW); }else if(temperature >= baselineTemp+2 && temperature < baselineTemp+4){ digitalWrite(2, HIGH); digitalWrite(3, LOW); digitalWrite(4, LOW); }else if(temperature >= baselineTemp+4 && temperature < baselineTemp+6){ digitalWrite(2, HIGH); digitalWrite(3, HIGH); digitalWrite(4, LOW); }else if(temperature >= baselineTemp+6 ){ digitalWrite(2, HIGH); digitalWrite(3, HIGH); digitalWrite(4, HIGH); } delay(1); }

第2節課

Project 04 Color Mixing Lamp 改變顏色
利用光敏電阻，當手壓著光敏電阻，讓LED燈該顏色不會亮。
我們的光敏電阻順序為:紅色、綠色、藍色
