When hacking with a Raspberry Pi Zero (or similar device), many makers use the General Purpose Input / Output (GPIO) pins. These pins are used to attach and control a wide range of devices such as LEDs or sensors to measure temperature, light, or humidity. However, if you prefer to code on your desktop or laptop this may be an issue since most of these devices don’t have accessible GPIO pins. This is where GPIO expander software can help.
The main goal of GPIO expander software is to use the Raspberry Pi Zero as an USB device connected to a
