Hello everyone,

I have a project I am working on and I want to add something similar to what is in the picture.
I need the numbers to change, the graphic doesn't have to (I can make a cutout and put an LED behind in)
Any idea which screens I can use?
I was looking around and saw the TFT. They are nice but might be a bit more complicated than what I need (especially since I never worked with screens before)
Anyone has different ideas?

Regards,
Patrick

 

Just curious... What are you using to drive the display? And how big is it?

I'd use a graphical LCD, like this one from Sparkfun. Presented for information only.

If you only need one colour, consider a small OLED display.

They are much cheaper on ebay.

 

I have note picked a controller yet. But most probably I will have to work with PIC microcontrollers. Is that possible?

Yes.

 

any examples to start from?

Different displays have different requirements. Graphic displays need more resources from the uC than text only displays. You need to choose a suitable display then look for code for driving it.
I have a 320x240 pixel graphic display being driven by a 20 pin PIC (PIC18F14K22) so there is no problem there.

I'm sure there are examples for the PIC if you look for them. There are also easy to use Arduino libraries for these displays available from Adafruit in the link I posted.
