Need Help on LCD And RTC
Need Help on LCD And RTC
Hi katchupoy,
Need your help to continue my work
My stuff not yet complete i try to write a code for LCD & RTC that is the stuff i got now.
so i need try for upload ur code for my LCD and RTC. I use this code and delete some code;

But i can't compile and upload the code, it said error like this;
