For a project I’m working on sending and receiving text messages to my Arduino Uno with a GPRS Shield V1.0. The end goal will be to parse the text, which will be an integer, turn an LED a specific color based on this value, and return an “OK” that it was received.
I have been following the Wiki verbatim to no avail. Partnered with this another I have been able to call to and from the GPRS shield as well as receive a text message. The only sketch on the Arduino is what is in the first tutorial the initial sketch.
Any help is appreciated greatly.
