Office Arduino Drone: Part III

The HC — 05 Bluetooth module finally came. Oh the feeling of seeing it in our mailbox right on time and then unravelling the packaging is an incredible feeling.

Please see our previous blog to get more context on this Blog Series.

HC-05 Bluetooth module has finally arrived into my breadboard!

What we’ve been able to do so far:

1. Successfully connect the HC-05 module to our breadboard and Arduino

Initial circuit diagram (shown above).

2. Successfully pair my computer with the HC-05 module wirelessly

What we’re currently working on:

1. I am having a flaky connection between my computer and the HC-05 module when paired. From doing some research online, there may be a conflict between the bluetooth port on my computer, and the Arduino module.
2. I am leveraging codebender.com to upload sketches to the devices from the tutorials I am reading, though I am having some trouble understanding why certain things are being used in certains ways (see next bullet).
3. Learning what the purpose of the Sudo Terminal. The tutorials both point towards downloading a new terminal, and I need to understand why I can not use my existing “iterminal” on MacOs.

My Dreams for this Project

1. Get a full blown understanding of all the elements used in this tutorial (both hardware and software)
2. Get the drone to respond properly to my bluetooth commands, either given by my computer, or TinyDuino
3. Successfully deliver pizza to our teammates in our offices via our Bluetooth Drone/Arduino fishing line mechanism!

Next week we hope to have more progress actually building the Drone. Thanks for tuning in! Please drop any comments you have that will help us build our office drone! We appreciate your help.
