I am having an issue with a readPPM. I am very new to coding and a lot of this is from other sources. I'm making a underwater robot that is controlled by RC signals and I keep getting 'readPPM was not declared in scope' when I have #include <PinChangeInt.h> in the beginning which is supposed to be for the readPPM. Any suggestions.
you have not read "other sources" carefully. when some library is used than there is instruction like "you need to get used libraries before compiling", sometimes they are present on that site to download, otherwise it should be found in net.
but i am happy that you at least not showing scanned photos of your monitor.
Read the instructions for how to post code and errors, the real error is likely earlier in the log.
