“Using an old VFD serial communication display for use with Arduino based microcontrollers.
I remember back in 2018 that I got this screen (from an old guitar pedalboard) and didn’t know how to make it work. I was just starting out in the Arduino world, and only knew how to operate a 16X02 display with the standard Arduino library.
With this display there were no libraries, and I only had the datasheet. With this I documented and it was that I understood in real life how UART communication works.
Fortunately, it didn’t take me long to discover the Arduino SoftwareSerial library.
So I set out to build the hardware-based functions of the VFD.
As a newbie I remember that the whole process took me like a week.
The best thing about this was that it taught me how to deal with life’s problems where resources are limited.”
