I am having trouble using the mega shiekld with the Arduino Mega ADK . Am trying to make an LED attached to the mega shield to blink , but it is not helping. Please help!
Sorry no idea what you are asking. You need to supply much more information. What shield are you using, what is the LED attached to, what have you tried so far?
So post links, post schematics and post your code. Read the how to use this forum sticky post before you post any code to know how to post code correctly.
