چگونگی اتصال ماژول sim 900 به اردوینو مگا و کار کردن با آن

[masiha427]

دوستان فقط ننویسید کارم راه افتاد. بگید دقیقا چطور کارتون راه افتاد
ماژولی که من خریدم: ماژول GSM با قابلیت اتصال GPRS و ارسال و دریافت پیامک Sim900A

تصویر سیم بندی


نکته1: اول که ولتاژ ماژول رو وصل کردید چراغ D6 (گوشه ماژول) سریع چشمک میزنه (1ثانیه یه بار) و بعد که آنتن گرفت آرومتر چشمک می زنه (3ثانیه یه بار)
نکته2: اگر رایتل استفاده می کنید یا باید خیلی صبر کنبد تا آنتن بیاد یا تو گوشی اپراتور رو به صورت دستی رومیگ کتید رو ایرانسل یا همراه اول
نکته3: توی کدنویسی شماره تلفن رو با 98+ شروع کنید
نکته4: کمی به قسمت انگلیسی مغز فشار بیارید و توضیحات اول کد رو بخونید

کد آردوینو مگا 2560

/*Note: this code is a demo for how to using gprs shield to send sms message,
dial a voice call and
send a http request to the website, upload data to pachube.com by TCP connection,
The microcontrollers Digital Pin 7 and hence allow unhindered
communication with GPRS Shield using SoftSerial Library.
IDE: Arduino 1.0 or later
Replace the following items in the code:
1.Phone number, don't forget add the country code
2.Replace the Access Point Name
3. Replace the Pachube API Key with your personal ones assigned
to your account at cosm.com
