Masih penasaran dengan cara kerja sensor ini, silahkan lihat video berikut ini terlebih dahulu

Adapun bahan yang di butuhkan adalah sebagai berikut :

1. Arduino Nano / Promini
2. Sensor IR E18 D-80
3. Relay 1 channel modul

Rangkailah seperti dibawah ini

 

Untuk Programmingnya bisa di lihat di deskripsi dari video sebelumnya di channel ini.

Selamat mencoba, Salam Arduino Indonesia

Arduino IOT Mengambil data lewat API (COVID-19)

Halo Sobat Arduino, Barusan saya post di video tentang bagaimana cara mengambil data dari website penyedia API untuk sebaran pasien COVID-19 di Indonesia.

Kalau belum lihat videonya, berikut videonya






Oke bahan yang di butuhkan adalah sebagai berikut :

• ESP8266 Modul IOT
• OLED 1.3"
• Kabel Jumper
• Projectboard

Susun Seperti berikut ini

Dengan susunan pin sebagai berikut :
OLED -->  ESP8266
GND    --   GND
VCC    --    3V3
SCL     --    D1
SDA    --    D2

Untuk API nya bisa registrasi dahulu du web berikut

http://covid.vinteq.in/api/

Silahkan registrasi untuk mendapatkan AUTH nya

Library yang di perlukan adalah sebagai berikut :

1. ESP8266WiFi (https://github.com/esp8266/Arduino/tree/master/libraries/ESP8266WiFi)
2. ESP8266HTTPClient (https://github.com/esp8266/Arduino/tree/master/libraries/ESP8266HTTPClient)
3. WiFiUdp (sama seperti library nomor 2)
4. NTPClient(https://github.com/arduino-libraries/NTPClient)
5. ArduinoJson(https://github.com/bblanchon/ArduinoJson)
6. Adafruit_GFX(https://github.com/adafruit/Adafruit-GFX-Library)
7. Adafruit_SSD130(https://github.com/adafruit/Adafruit_SSD1306)

Program arduino untuk Alat pengingat Cuci Tangan

Halo sobat Arduino Indonesia, gencar gencarnya cuci tangan pada saat ini guna menaggulangi virus corona atau covid-19. kami sendiri yang sering lupa untuk cuci tangan ketika masuk rumah, berinisiatif untuk membuat alat yang bisa membantu mengingatkan buat cuci tangan.

Bahan-bahan yang diperlukan adalah sebagai berikut :

1. Arduino nano 
2. Sensor ultrasonic 
3. Mp3 Player (DFPlayer mini) 
4. Speaker 
5. Breadboard 
6. Kabel Jumper

untuk penyusunan pengkabelan bisa di lihat di video berikut :

Coding untuk Project Alat pencuci tangan Otomatis adalah sebagai berikut :

/*

 #include "Arduino.h"
#include "SoftwareSerial.h"
#include "DFRobotDFPlayerMini.h"
#include <NewPing.h>

#define ECHO_PIN     7  // Arduino pin tied to echo pin on the ultrasonic sensor.
#define MAX_DISTANCE 200 // Maximum distance we want to ping for (in centimeters). Maximum sensor distance is rated at 400-500cm.

  Serial.begin(115200); // Open serial monitor at 115200 baud to see ping results.
Serial.println();
  Serial.println(F("DFRobot DFPlayer Mini Demo"));
  Serial.println(F("Initializing DFPlayer ... (May take 3~5 seconds)"));
 
  if (!myDFPlayer.begin(mySoftwareSerial)) {  //Use softwareSerial to communicate with mp3.
    Serial.println(F("Unable to begin:"));
    Serial.println(F("1.Please recheck the connection!"));
    Serial.println(F("2.Please insert the SD card!"));
    while(true){

  myDFPlayer.play(1);  //Play the first mp3
}

Arduino Sensor Suhu Infrared

Hallo Sobat arduino,

Sensor suhu contactless atau bisa kita sebut sensor suhu thermogun sekarang ini sangat langka, dan mahal harganya. maka dari itu kami dari Sekolah Robot Indonesia membuat produk baru dan dijadikan tutorial membuat sensor suhu contactless yang terhubung langsung dengan smartphone.

adapun langkah langkah pembuatannya bisa dilihat di youtube

https://youtu.be/O9Yt_CN5G8w

Untuk coding arduinonya sebagai berikut:

/*
 * MLX90614 Send to OTG
 * Dhadhang SBW
 * Sekolahrobot.com
 */

#define LED 13
#include <Wire.h>
#include <Adafruit_MLX90614.h>

Adafruit_MLX90614 mlx = Adafruit_MLX90614();

unsigned long previousMillis;
int interval = 50;
char i;
int data = 0;
void setup() {
    Serial.begin(9600);
    mlx.begin();
    pinMode(LED, OUTPUT);
}

void loop() {
    if (Serial.available() > 0) {
        i = Serial.read();
        switch (i) {
            case '0':
                digitalWrite(LED, LOW);
                data = 0;
                break;
            case '1':
                digitalWrite(LED, HIGH);
                data = 1;
                break;
        }
    }
if (data==1)
  {
      if (millis() - previousMillis >= interval) {
          previousMillis = millis();
          Serial.print(mlx.readAmbientTempC());
          Serial.print(";");
          Serial.println(mlx.readObjectTempC());
      }
  }
