I bought a mux shield 2 few days ago and it is not working as i wanted it to work.
if I make all I/O as output and call any one pin from I/O 1 as HIGH and then calls any other pin from I/O 2 or I/O3 as LOW or HIGH the pin from I/O 1 gets LOW which I set as HIGH .
This case applies to I/O2 and I/O3 also if I replace I/O 1 with I/O 2 or I/O 3.
And there is no soldering problem I have checked it .
Please help me out with this problem and I am also attaching my code , please have a look to my code also
