Contoh code program 2 :

#include "SevSegShift.h"#include

SevSegShift sevsegshift;byte tmp[16] = {252, 96, 218, 242, 102, 182, 190, 224, 254, 230, 238, 62, 156, 122, 158, 142};byte tempPin = 0;float scaler = 0.004882814;volatile float temperature;volatile word counter = 0;

6. Sensor HCSR04/ultrasonic

#include

#define TRIGGER_PIN 12#define ECHO_PIN 13

Ultrasonic ultrasonic(TRIGGER_PIN,ECHO_PIN);

voidsetup(){ Serial.begin(9600);}

voidloop(){floatcmMsec,inMsec;longmicrosec=ultrasonic.timing();

cmMsec=ultrasonic.convert(microsec,Ultrasonic::CM); inMsec=ultrasonic.convert(microsec,Ultrasonic::IN); Serial.print("MS: "); Serial.print(microsec); Serial.print(", CM: "); Serial.print(cmMsec); Serial.print(", IN: "); Serial.println(inMsec); delay(1000);}

Kalau tidak ada pesan error maka modul ultrasonic akan langsung bekerja mengukur jarak benda di depannya. Gunakan Serial Monitor (Ctrl+Shift+M) pada software Arduino untuk melihat hasil pengukuran.

voidloop(){ sensorValue=read_sdm_io_range(); Serial.print(sensorValue); Serial.println(" cm"); delay(100);

}
