hello friends, im just beginner with arduino,and wrote some code to operate arduino MEGA by sim900 shield with DTMF commands, but it is not working. please help to make working that.i wrote before code which operates by SMS commands, and now have to transform it for DTMF, but not working, i had losse something.how to use serial buff explain please. when we use dtmf in the terminal is shown next
There is a sticky at the top of the forum that you should have read BEFORE posting in this forum. Clearly, you didn't. Once you read that sticky, you'll know why I'm certain that you didn't read it first.
sorry friend if i had write something incorrect.im just want to learn to work with that shield.im new to arduino, and googled all internet for dtmf using there,but didn't find. if there are also people who try that lets work together for some result
You got the results you showed using some code, which you didn't show. The sticky at the top of this forum says that if you post here, you post your code. Otherwise, we have no idea why you are not getting what you expect, or how to help you modify the code to get what you need.
sorry, yes really i forgot to post code for controlling an objects by SMS. but i just now have solved my problem, i wrote code that using DTMF for controlling.
