Hello out there... i been working on this program that i found in YouTube. that make the Arduino in to a oscilloscope. the program works great.. but i want to remove the Swicth that are use to set some value that i want to make static. now i have tryed to do this for 3 weeks now and im not geting anywhere.. if anyone can help me out. that would be Great and thank you..
Here is the orginal code..
