Arduino and HC-05/HC-06 Bluetooth Module Complete Tutorial

by
Arduino Bluetooth Tutorial HC-05 Bluetooth Module

This tutorial walks through the HC-05 and HC-06 Bluetooth modules with Arduino. You’ll wire up the module, control an LED over Bluetooth, build a basic app in MIT App Inventor, and then take it further with relay-based lamp control. I also cover the common issues people run into and a few frequently asked questions.
