IMPORTANT -- Since I first published this video, I've made several clarifications to my web page on this topic that people trying to use Arduinos that have on-board USB to Serial Adapters will need to understand.
11-26-2017 - As this seems to be one of my more popular videos, Ive decided to work on an updated video (and web article) that I hope to publish in the near future that will cover additional ways to use HC-05 modules. If there are specific issues you'd like me to cover, or demonstrate in more detail, please post a comment below. I can''t guarantee I can address every question, or issue, but I'll do my best.
