i am new in the arduino section and want to make a temperature, humidity and differential pressure reading guide with 2004 lcd (not I2c) , one DS3231, ads1115 (0X4A) with mpxv5004DP sensor on A0 port of ads1115, HTU21D (for temperature and Rh), infrared receiver HS0038A (for set menu using remote) and arduino nano.
i want to make this with a menu function in it for change the values, like set date and time and differential pressure in Pa or mmwc, temperature in C or F, and offset values for calibration purpose.
I don’t know everything or something about programming. i found a lib for lcd menu which is LCDmenuLib.h
from which i edit some function but don’t know what i do next please help me for enabling and desabling the menu, i want to make this just like a product which has functions and working correctly with them.
also i want to know can we connect more then one arduino nano(more then 10 or 100) on rs485 cable in serial to take the data in PC, which software you suggest for reading temperature, humidity and differential pressure data saperately in non editable format.
