IR_sensor /Digital

• IR_sensor(int pin) // constructor
• detect() // return 0 or 1, need to change the resistance

Smoke_sensor /Analog

• IR_sensor(int pin) // constructor
• value // return int value
• detect() // return 0 or 1, affect by treshold

Sound_sensor /Analog

• IR_sensor(int pin) // constructor
• value // return int value
• detect() // return 0 or 1, affect by treshold

Buzzer /Digital

• IR_sensor(int pin) // constructor
• on() // Buzzer on
• off() // Buzzer off

Ultrasonic Sensor

• Ultrasonic_sensor(int trig, int echo) // constructor
• value() // return int value(with smoothing)

Photocell Sensor

• Photocell_sensor(int trig, int echo) // constructor
• value() // return int value(with smoothing)

Accelerometer

• Implementation like lab
• GY80 sensor = GY80(); //create GY80 instance
• GY80_scaled g_value = sensor.read_scaled();
• g_value.a_x , g_value.a_y, g_value.a_z. //x,y,z acceleration
