Monochrome LCD and Arduino

Would there be any way to interface this monochrome LCD with the Arduino and only use about 4 pins? I only need to use the 3 segments in the middle.

there are LED driver ships out there, I'm not sure how many pins you will need with one of those though.

you could always grab one of these http://www.wulfden.org/k107/order.shtml

a bit more than 2 bucks, but a lot cheaper than similar serial lcds.

It s pretty good price for what you get, though it is not open source. It only needs 3 pins. power, gnd, and one for serial input.

I got one recently and I have to say it was really easy to assemble and use.

This one will probably be tricky because it wants AC to work not DC.

Thats for a character LCD. Not a segmented LCD.

According to the datasheet, it looks like the best you'd be able to do (without extra circuitry) would be 10 pins to control those three digits in the middle. There are two pins for each digit (8, 9, 10, 11, 14, 15) and four common pins (17, 18, 19, 20) that you need to drive. If you added a chip (like a 4-bit shift register) that you could clock to drive each of the common pins in turn, you could get that down to 7 Arduino pins. Either way, this looks like a fairly specialized LCD, and the standard LCD drivers aren't going to help you; I imagine you'll have to write your own control code.
