Watif:
Hey guys ! I'm working on a project, SMS Based LED Matrix Display. this would display messages sent from a mobile phone to an LED matrix. I already did it but it's only can display 15 character. I want to display more than that but it's not working. Anyone can help me on this ? As soon as possible. I'm using arduino Mega AT2560 and SIM900a. Here is my code.
Hi Watif, can i use this same code for SIM800L
