PROGRAM SMS MENGGUNAKAN ARDUINO

Assalamu’alaikum Wr. WB

kali ini saya akan menjelaskan

tentang tata cara pembuatan

jam digital pada aplikasi java eclipse

saya sangat berharap postingan  ini

dapat berguna dalam rangka

menambah wawasan serta pengetahuan

pertama alat alat yang digunakaN

1. arduino uno v3.0

2. gsm module SIM900A

3. 4 kabel jamper

4. 1 led

5. 1 kabel penghubung serial port

6. 1 buah kartu gsm

dibawah ini adalah foto rangkainyannya

keterangan :

• kabel warna hijau  (Arduino pin  02  —->GSM Module 5VT  )
• kabel warna putih (Arduino pin 03 ——>GSM Module  5VR )
• kabel warna hitam (Arduino GND —–>GSM Module GND )
• kabel warna hitam  (Arduino 5V ——> GSM Module  VCC5  )
• led  (led negatif –>GND)
• led  (led positih –>pin13)

dan di bawah ini code arduino

/*
SMS sender
 
This sketch, for the Arduino GSM shield,sends an SMS message
you enter in the serial monitor. Connect your Arduino with the
GSM shield and SIM card, open the serial monitor, and wait for
the "READY" message to appear in the monitor. Next, type a
message to send and press "return". Make sure the serial
monitor is set to send a newline when you press return.
 
Circuit:
* GSM shield
* SIM card that can send SMS
