For the LEDs, yes For the neon bulbs, remove the 100K series resistor. The transistor is a current-limiter. I took a wild guess at the operating current being 1mA; check the datasheet for DC operation. Be aware that neon bulbs wont last as long on DC vs AC, roughly 60% lifetime per datasheet.
If you have 2 extra pins on the arduino, you can run the neon bulbs on AC with 2 additional transistors + resistors. If that's desirable for you, go back to your original design and make a few changes: 1. 160 VDC --> 100K resistor --> NPN transistor collector. Instead of 2, you will need 4. Note that the neon bulb is NOT connected in-series. 2. Arduino_output --> 10K resistor --> NPN transistor base 3. Connect 1 neon bulb terminal to NPN collector 4. Alternately turn the NPN devices on at 50% duty cycle. This will drive an AC square-wave on the neon bulbs. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
