Please add code tags

All you are doing is posting code you are finding online. One more time exactly what happens on the screen? Exactly how are things wired? Your last code does not even include a display. Nobody can work with what you are posting. You are leaving important questions you are asked out. List a link to your display. Exactly the display you have, not a picture but a link to a data sheet.

Comment before you know. That code is for mine project for CO2 sensor analogous data which based on relay operation with thresold.

You can get it from 1st post

Ron_Blain · October 18, 2022, 12:46am

All you posted is a plain picture of a screen. That was your second post, post #3. Your last code made no mention of a display? A picture of a display is not useful at all. Make/Model a link to a data sheet? I get what you are trying to do, a CO2 sensor likely a MQ2. These are inaccurate but ok for a hobby toy. Hopefully another member can help you.

Please help me to display the data directly through TFT display

shuvra100 · October 18, 2022, 11:06am

Please help me to display the data post #1

UKHeliBob · October 18, 2022, 11:15am

Where are you stuck ?

Have you printed anything at all to the screen and if so, what data type was it ?

shuvra100 · October 18, 2022, 11:44am

Please modify the code of post 1# to display on OLED

Without sensor connection -----how it is coming ?

Please

Ron_Blain · October 18, 2022, 3:31pm

Yes, with the open floating input it looks about right. Running that code on an Arduino UNO if I apply 0.0 volts (ground) I get analog input = 0 and scaled value = 0. Apply 3.3 volts and I get analog input = 687 and scaled value = 20 just as expected.

Next to get this on your display the make and model of the display need to be known. There are many TFT displays and associated libraries.

I need 2 things to know -

1)OLED display of sensor data
2) How to measure voltage from multimeter& associated logic % for co2

shuvra100 · October 19, 2022, 3:09am

Relay pin is not operational

TomGeorge · October 19, 2022, 3:37am

Hi,

Can you please tell us your electronics, programming, arduino, hardware experience?

Sorry, but we need to know your level of knowledge?

Is this a school/college/university project?

Did you write this code or is it from another source?

Thanks.. Tom...

shuvra100 · October 19, 2022, 3:42am

?

TomGeorge · October 19, 2022, 6:46am

Hi,

What is the lead from, is it AC or DC?
