So I am just a beginner and is currently learning to use Arduino Sketch. My problem is that, when I verify the commands I use, there are no mistakes. However, when I try to upload it, the software will say that there are errors in my program. Like,
C:\Users\Acer\Documents\Arduino\sketch_mar23c\sketch_mar23c.ino:32:22: warning: ISO C++ forbids comparison between pointer and integer [-fpermissive]
