AlxDroidDev:
I suggest the MAX7219 or MAX7221Each MAX7219/7221 can drive up to 8 digits of 7-segment display. They are easy to work with (SPI, 3-wire) and daisy-chainable. They also come in 24-pin DIP packages AND there is an automotive version available (which I think might suit you better than the regular version).
There is plenty of examples out there that uses the MAX7219 with Arduinos, driving either led matrices or 7-sd's
Hi AlxDriodDev,
I was tending towards the MAX chip, but I like the comments from GrayNomad as well. Found this link this afternoon
Too cheap to be true, and note that the 4 digit displays are mounted in machined headers making them removable, but, it still doesn't fit my requirements unless I do a re-think.
Does anybody know of a reliable supplier of red/green 4D7Seg displays?
