6. PRESSURE BAROMETER BMP 180
/* SFE_BMP180 library example sketch This sketch shows how to use the SFE_BMP180 library to read the Bosch BMP180 barometric pressure sensor. https://www.sparkfun.com/products/11824 Like most pressure sensors, the BMP180 measures absolute pressure. This is the actual ambient pressure seen by the device, which will vary with both altitude and weather. Before taking a pressure reading you must take a temparture reading. This is done with startTemperature() and getTemperature(). The result is in degrees C. Once you have a temperature reading, you can take a pressure reading. This is done with startPressure() and getPressure(). The result is in millibar (mb) aka hectopascals (hPa). If you'll be monitoring weather patterns, you will probably want to remove the effects of altitude. This will produce readings that can be compared to the published pressure readings from other locations. To do this, use the sealevel() function. You will need to provide the known altitude at which the pressure was measured. If you want to measure altitude, you will need to know the pressure at a baseline altitude. This can be average sealevel pressure, or a previous pressure reading at your altitude, in which case subsequent altitude readings will be + or - the initial baseline. This is done with the altitude() function. Hardware connections:
- (GND) to GND + (VDD) to 3.3V (WARNING: do not connect + to 5V or the sensor will be damaged!) You will also need to connect the I2C pins (SCL and SDA) to your Arduino. The pins are different on different Arduinos: Any Arduino pins labeled: SDA SCL Uno, Redboard, Pro: A4 A5 Mega2560, Due: 20 21 Leonardo: 2 3 Leave the IO (VDDIO) pin unconnected. This pin is for connecting the BMP180 to systems with lower logic levels such as 1.8V Have fun! -Your friends at SparkFun. The SFE_BMP180 library uses floating-point equations developed by the Weather Station Data Logger project: http://wmrx00.sourceforge.net/ Our example code uses the "beerware" license. You can do anything you like with this code. No really, anything. If you find it useful, buy me a beer someday.

The buzzer in your Inventor's Kit is an electromechanical component you can use to make noise. Inside the buzzer is a coil of wire and a small magnet. When current flows through the coil, it becomes magnetized and pulls towards the magnet, creating a tiny "click". When you do this thousands of times per second, you create tones. The Arduino has a built-in command called tone() which clicks the buzzer at a certain frequency. This sketch knows the frequencies of the common notes, allowing you to create songs. We're never going to let you down! Hardware connections: The buzzer has two pins. One is positive and one is negative.
The postitive pin is marked by a "+" symbol on both the top and bottom of the buzzer. Connect the positive pin to Arduino digital pin 9. (Note that this must be a PWM pin.) Connect the negative pin to GND. Tip: if the buzzer doesn't fit into the breadboard easily, try rotating it slightly to fit into diagonal holes. This sketch was written by SparkFun Electronics, with lots of help from the Arduino community. (This sketch was originally developed by D. Cuartielles for K3) This code is completely free for any use. Visit http://learn.sparkfun.com/products/2 for SIK information. Visit http://www.arduino.cc to learn about the Arduino.

47. PENGHITUNG RAKAAT SHOLAT Program inin adalah gabungan dari beberapa program elementer, antara lain : program untuk menjalankan LED matrix, program untuk menjalankan ultrasonic sensor, program untuk menjalankan counter serta untuk push button. Pada proyek ini kita menggunakan sensor ultrasonic untuk mendeteksi jarak antara sensor dan kepala ketika sujud. Sensor ultrasonik kita pasang pada board arduino signal (sensor unit), hal ini dilakukan untuk mengisolasi sensor ultrasonic, karena sensor ultrasonic ini akan terganggu jika dipasangkan pada satu board dengan counter, yaitu pengukuran jarak menjadi tidak stabil ketika sensor ultrasonic ini tergabung dalam satu mikro kontroler. Prinsip garis besarnya adalah sensor ultrasonic akan mengukur jarak antara kepala dan sensor, ketikajarak sensor dan kepala lebih kecil dari 30 cm maka pin D7 akan menjadi HIGH, signal HIGH dari pin D7 ini akan di-injeksikan ke pin D2 pada board arduino counter, yang pada dasarnya pin D2 arduino counter ini adalah eks push button, signal yang dihasilkan oleh push button kita gantikan dengan signal dari D7 dari board sensor. Ketika jarak sensor antara 30 hingga 80 cm pin D7 tidak berubah status, sedangkan ketika jarak sudah lebih dari 80 cm makan pin D7 akan berubah menjadi LOW. Hitungan dari board counter akan ditampilkan pada display 2x LED matrix 8x8.

87. SEND DATA VIA BLUETOOTH
Module bluetooth ini pada dasarnya berguna untuk mengirim data yang tertampil pada monitor serial ke klien atau pair. Data dari arduino dikirim melalui pin RX dan TX. Sebagai contoh kita akan mengirim data pada pin A0, void setup() { // initialize serial communication at 9600 bits per second: Serial.begin(9600); } // the loop routine runs over and over again forever: void loop() { // read the input on analog pin 0: int sensorValue = analogRead(A0); // print out the value you read: Serial.println(sensorValue); delay(1); // delay in between reads for stability } Pertama-tama kita lepas dahulu kabel pin TX dan RX dari arduino, kemudian kita upload kode di atas, lalu kita sambungkan lagi kabel ke pin RX dan TX arduino, maka data telah dipancarkan lewat bluetooth. Untuk membaca data via bluetooth maka kita memerlukan komputer yang dapat mengakses signal bluetooth. Jika kita menggunakan Windows 10, aktifkan bluetooth dengan cara klik ikon bluetooth pada task bar ---> Show Bluetooth Devises, maka pada tampilan Manage Bluetooth devices akan tertampil HC-05, klik lalu lakukan pair, akan diminta password, isikan 1234 sebagai password, maka bluetooth siap diakses. Cara mengakses data yang terkirim via bluetooth dapat kita lakukan dengan membuka Arduino IDE versi 1.6.xx. Arahkan port ke port yang digunakan oleh bluetooth, kemudian buka serial monitor, maka data yang terkirim via bluetooth akan tertampil. Cara lain untuk mengakses data via bluetooth ini adalah dengan sofware Tera Term, kita bisa
download secara gratis. Setelah kita install kita open maka akan tampil menu koneksi, pilih serial serta pilih port yang dipakai bluetooth, maka data akan tertampil. Kelebihan Tera Term ini kita bisa simpan data yang tertampil dengan cara data log ke suatu file notepad. ===================================================================

90. WATERBATH
Pada diagram di atas kita sajikan draft waterbath. Garis besar cara kerjanya adalah sebagai berikut. Temperatur dari air dalam wadah diukur dengan PT100, signal dari PT100 ini diperkuat dengan penguat LM324, output dari LM324 ini diumpankan ke ADS1115, di mana modul ADS1115 ini akan meningkatkan resolusi pembacaan signal analog dari output LM324. Signal analog yang dibaca kemudian dikalibrasi terhadap rentang suhu. Pembacaan suhu ini akan digunakan untuk mengendalikan sebuah pemanas listrik melalui relay. Relay tidak terhubung secara langsung terhadap sirkuit kontroler, karena jika relay ini tergabung pada sirkuit kontroler maka akan menimbulkan ketidakstabilan pembacaan suhu, sebagai gantinya maka kita gunakan gabungan LED dan LDR untuk mengaktifkan relay ini. Sumber tegangan yang dipakai kontroler dan relay juga terpisah. Hal yang tak kalah penting adalah pisahkan ground untuk ADS1115 terhadap ground yang digunakan module lain agar stabilitas pembacaan suhu terjaga. #include #include int pinIncrease = 2; //pin increase button int pinDecrease = 3; //pin decrease button int pinHeater = 11; // go to relay input int pinIND = 13; // LED heating indicator int pinSetting = 10; // setting temperature button key int SettingSuhu = 0; byte BatasSuhu; //---------------------------temp section #include #include Adafruit_ADS1115 ads(0x48); int temp0; //---------------------------temp section LiquidCrystal lcd(4, 5, 6, 7, 8, 9);//order number : RS,EN,D4,D5,D6,D7 void setup() { Serial.begin(9600); lcd.begin(16, 4); //---------------------------temp section ads.begin(); //---------------------------temp section pinMode(pinIncrease, INPUT); pinMode(pinDecrease, INPUT); pinMode(pinSetting, INPUT); pinMode(pinHeater, OUTPUT); pinMode(pinIND, OUTPUT); digitalWrite(pinIncrease, HIGH); digitalWrite(pinDecrease, HIGH); } void loop() { if(digitalRead(pinSetting) == HIGH){ int16_t adc0; // we read from the ADC, we have a sixteen bit integer as a result adc0 = ads.readADC_SingleEnded(0); temp0 = adc0; float suhu = (temp0*0.030705394)-364.87967;//from calabration plot SettingSuhu = constrain(SettingSuhu, 0, 255); setting();
