Programmable Timer 8Channel dengan Arduino Uno

Membuat Programmable Timer 8 Channel

Mengendalikan 8 buah Relay dengan batas waktu tertentu untuk setiap relay-nya

Pada Tutorial kali ini kita akan membuat sebuah project pengendalian beban/relay dengan methode Timer, yaitu setiap relay dapat kita program jam berapa harus ON dan jam berapa harus OFF.Setiap relay memiliki 1 settingan timer sendiri sehingga mempunyai waktu masing-masing kapan harus ON dan OFF.

Disini kita menggunakan memory EEPROM internal atmega328 (Arduino Uno) untuk menyimpan data settingan timer sehingga kita akan kehilangan settingan saat Power mati (mati listrik) atau saat Arduino Restart/reset.

A.Bahan dan Module yang dibutuhkan

-1Unit Relay Module 5V 8 Channel
-1Unit RTC DS3231
-1Unit Arduino Uno/Nano/Pro mini/Mega
-1Unit LCD 1602 dengan i2C connection
-4Unit Tombol Tactile Push Button (momentary switch)

B.Wiring  

Perhatikan Gambar pada header artikel ini.

C.Library

-Library EEPROM (sudah include dalam sistem Arduino IDE)
-Library Wire.h (sudah include dalam sistem Arduino IDE)
-Library RTC DS3231 silahkan download disini.
-Library LiquidCrystal_I2C silahkan download disini.
-Library Push Button silahkan download disini.


Setelah anda mendownload semua library yang dibutuhkan dalam project ini,silahkan extract terlebih dulu dari .rar/.zip file nya kemudian copy semua folder master library tersebut (misal : folder button-master) ke dalam folder "libraries" yang ada di folder installer Arduino IDE.

D.Sourch Code

Berikut Sourch Code Untuk Tutorial kali ini.Silahkan copy paste code berikut ke dalam Arduino IDE anda kemudian Upload ke Arduino Boar.
