Hello mate ... I was watching carefully you video but when I try to follow you example I discovered that You PUT twice the "void setup" function and Twice "void loop" function, so the Arduino IDE cannot execute that .... and that 34 line "Sketch to read time, date & temperature & display on MAX7219 8x32 Dot Matrix display: - Arduino Can't pass that line also .... SO Please can You check again and see what's wrong with it ?. ... Thank You Best Regards

@@AnasKuzechie Good morning, thanks for reply. The library is installed correctly. I also tried from the Arduino ide, it says it is an invalid library. : Arduino: 1.8.19 (Windows 10), Board: "Arduino Uno" count0to99: 6: 10: fatal error: MAX72198by32Disp.h: No such file or directory #include ^ ~~~~~~~~~~~~~~~~~~~ compilation terminated. exit status 1 MAX72198by32Disp.h: No such file or directory This report could be richer in information by enabling the option "Show verbose output when compiling" in "File -> Settings" thank and have a nice day
