I  am going to start working on some Arduino projects because of my new living space limitations. I wanted to learn how to add bluetooth capability to my projects so I ordered a DSD Tech HC-10 bluetooth module.  I read a few tutorials to get familiar with how the module worked and wired up a simple LED light tutorial. The code provided needed to be modified as it was missing a declaration for a pin as an output. This took a few minutes to figure out why the light wasn’t working. I verified everything else was working except this pin through the serial monitor.  After I fixed the code, I used the app tutorial to check that everything worked. A video is shown below of the LED light being turned on/off via Bluetooth through the app.
