IV-3 VFD shield for Arduino

6 Final test

Upload the demo sketch from the

Axiris website to the Arduino and

disconnect the Arduino from the

computer's USB port.

Plug the finished IV-3 VFD shield

on top of the Arduino. Make sure

no metal part of the Arduino

touches the solder joints of the

IV-3 VFD shield.

Connect

the

DC power

adapter to the Arduino power

connector and turn the power on.

After a few seconds the VFD tubes

should start counting from 0 to 9

in an endless loop. The decimal

separator dots of the VFD tubes

should form a binary 4 bit counter.

Tube

backlighting

should

dim

every few seconds and turn on

again.

Check the tube filament wires

carefully. They should glow very

faintly with a deep red color. If

they are glowing too much, lower

the values of C2 and C3. On the

other hand, if the filament barely

glows and the digits are too dim,

you can experiment by increasing

the values for C2 and C3.
