Reusing Light Emiting Diode Modules
I have a few LED (light emitting diode display) modules, recovered from various scrapped devices, that I wish to use in Arduino projects. They vary from 1/2” high single digit displays to tiny multi digit calculator displays.
Overview
Many older devices use LED displays for numeric readouts, less commonly they are used for alphanumeric displays.
LED modules
On the sidebar there is a list of LED modules, the linked pages include pinouts and whether there is an Arduino driver for them.
