6.7 Test the Neons
After soldering the four neons, be sure to quickly power up the
clock. All neons should light with uniform brightness.
This test is more important than just testing the neons,
because it confirms the clock is working before the next
stage of installing the RGB LEDs. Installing the RGB LEDs
can be a major reason for the clock not working at the end,
due to solder bridges on the RGB pads. Having done the
above test, you will know the reason is due to one of the
RGB LEDs.
