IR Remote Decoder With OLED Display

Introduction

For many projects, we might need to use an IR receiver for remote controlling many aspects of the project using an IR remote.

So while coding we need to hard code the decoded IR signals in our program so to make that job easy we are just going to build a small circuit with an Arduino nano, IR receiver and an OLED to display the decoded signals.
