Can any show me how to connect dht22 temp and humidity sensor and 2.4 tft lcd (like in picture bellow) to arduino uno r3 to show me temp and humidity on lcd. Can't find the example for my lcd, i know how to connect sensor only to arduino and monitor temp and humidity on serial monitor. And can you show me the code for arduino also.
Thanks in advance.
You do not really tell us much about your screen, ie chip set, modes etc.
Did your supplier not link you to some sample display programs for it ?
You could look here for some programs though a lot of such programs might be too big/use too many i/o or rather slow on a Uno, a Mega2560 is often prefered these types of screen.
Hi, you should check this out: MCUFRIEND_kbv Library for Uno 2.4, 2.8, 3.5, 3.6, 3.95 inch mcufriend Shields - Displays - Arduino Forum
It is ready to plug over the UNO as a shield and very well explained each example inside the library.
This is 2.4 tft lcd i bought

Chip on arduino uno r3 is saying Aimel MEGA 328P (or 320P) AV1540 (or 154D)
I can use examples on lcd, etc. tftpaint, graphic tester and everything work..
I know how to connect dht22 to arduino and watch temperature on serial monitor.
But i don't know how to combine the lcd and dht22 so i can watch temperature and humidity on lcd instead monitor. If i had some code or schematic help i would do it easy, but i'm very bad at code.
Thanks
