Interfacing Raspberry Pi with Explorer Hat

In this article we will learn how to make Explorer Hat for Raspberry Pi.

In the last post we will learn how to make Raspberry Pi with GPIO Expender MCP23017. You can visit our website,
I hope you appreciate my work, let’s discuss about today’s project.

Components:

Raspberry Pi (Pi 3)
Explorer Hat
