This is a quick tutorial on getting a VFD working with an Arduino (or Arduino equivalent system). VFDs are beautiful devices with a wonderful hexagonal mesh of wires and this lovely green/blue glow. Operating at around 5V, they offer a nice alternative to high voltage Nixie tubes, while still retaining a lot of the charm.
This tutorial will show you how to connect a Arduino-like device to a VFD display as well as a basic program to display text.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
