Afternoon all, I am desperately seeking help here!
I have searched the inter webs High and low and on here as well and I can't find a solution to a shudder issue I have.
I have the Spark fun Redboard (Uno 3) and their MG2639 Cellular Shield.
I want to be able to control a single servo from a text message.
I am able to get SMS messages successful with the example code and can control the servo's successfully with the example code.
However when i combine them the servo gets like a pulse jitter.
Notes: I have already tried ServoTimer2 and it made no difference.
I am powering it from a 2A power source.
I have tried about 7 different servo's and they all do the same thing.
I have tried placing the servo's on different pins and the results are the same.
Update: Solved it by using a much older library
Another Update: It works but still picks up signals from the GSM card as it gets the messages, causing the servo to jitter for 2 seconds.
