I have a simple arduino UNO-based weather station going. It just measures temperature, wind and humidity and prints on my laptop via the Serial Monitor feature.
Now i want to lift my game a bit. Ideally I would like a system that displays the data every 24 hours in a graphical format, Y axis = magnitude and X = time in hours. So there would be three plots, one for temperature, wind and humidity.
The unputs are all 0 to 5 volt analog and I would like to supply power with a simple 9 volt “wall wart” type transformer.
I have written quite a few sketches that actually compile! I understand a little more about libraries and how to implement them. I seem to be using braces correctly …just trying to say that i’m gaining confidence.
I have looked at the SF tft and oled screens… and there are some instrucables that i’m reading now…at this stage i am really open to suggestions what is a good SF display to try…easiest to learn is my priority.
Any suggestions welcomed.
Not committed to UNO, other boards may be better?
Goal is to have a stand-alone display of data
It really depends on your preference. How big you want it, etc. But I will tell you that OLED are harder to implement than something like a LCD 16x2 or 20x4. OLEDs are nicer and have better graphics though. So it just really depends on what you want in the end.
Thanks for the warning.
EDIT: After a few googles I found this: https://www.arduino.cc/en/Tutorial/TFTGraph
that is just the level I can handle.
Still interested in suggested displays. I would like to start with basics but continue to doll the interface up as I learn.
Original post:
No. 1 is “can i implement it?”
No. 2 is will the product be around for a while…i’d like to do other projects with the same hardware
I wanted something with more umph than 16 X 2 LCD. This time I was thinking of something like the uLCD-43P. Its the right size…great resolution and I feel more confident with serial data. I don’t go to the pub or bet the ponies so I’m thinking, you know, because i’m worth it.
is there a text or website to read up on making an x y plot?
I got a cheap screen, 3.95 inch ili9341 driver that works. Using examples I am able to modify to make plots.
BUT this screen uses all of the analog inputs on my Uno. How am I to display data without input??
BTW/ all of the graphs instructables or other sites are not useful. Dmainmon is fishing for food, others don’t work. I’m going to do this thing. any help appreciated
