You can also use an HT16K33 chip which controls both the anodes and cathodes and regulates the current so you can dispense with the resistors. It's a neat chip, and can optionally read a bunch of switches as a bonus. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
