I need help here.. im try to run my coding which i want to show on lcd. but i dont know how to make a coding so that lcd will show each reading one after another..start with temperature then moisture followed by carbon. but from my coding below,it juz read temperature..totally need your help
- CODE: SELECT_ALL_CODE
