Hi. I'm trying to make a small project that requires two 7 segment displays. I'm using a PIC 16F818 to run it. Due to the limited pins I multiplex(?) two 7 seg LEDs together using npn transistors. This seems to work pretty good, but I was wondering if I use LCDs instead...
Can I multiplex LCDs as I could with LEDs?
Battery life should be longer?
Do I need a resistor in series with each segment, if so, any idea how much?
I realized that the LCDs that I ordered (Mouser part# 696-LCD-S301C31TF), if I read the data sheet right operates on 5VAC and I'm using 5VDC. Will this work?
Any thoughts are welcomed. Thanks in advance.
