My Arduino Story: Part II
In my previous blog — “My Arduino Story — Part I” — I explained that I wanted to explore building a drone with a retractable fishing line attached, that could fly safely indoors to drop stuff off like pizza to people working at our coworking space. I asked for input from users and our 80,000 Facebook followers (likers) regarding certain questions I had regarding this project. This week’s blog - which consists of 5 parts: The Circuit, The Drone, The Budget, Next Steps, and Why Join — reveals the responses we received.
[1: The Circuit Schematic] We have made a lot of headway here by talking to our community, and we have now begun to collaborate on the actual circuit. One of my core concerns was how can we leverage the TinyDuino game controller, and its associated Tiny Bluetooth Module, to connect to the Arduino Uno’s associated Bluetooth module. The reason I was apprehensive here was because I sensed there was a fundamental difference between connecting a bluetooth module to a pc/phone, and connecting a bluetooth module to another bluetooth module. What we learned is that my gut was right.
Bluetooth wireless standard actually comes built in with the concept of “slave” and “master.” So it requires that we set the Arduino’s bluetooth module as the “slave”, and the TinyDuino’s bluetooth module as the “master.” This provides a lot of clarity to the build. However, I still request input as to whether it is possible to do this with the TinyCircuit, as displayed in the video above? (i.e., the instructor leverages a physical connection between the two devices using usb.)
The TinyDuino game controller and bluetooth module must be set as “role =1”, making it the master module, thus enabling us to control the Arduino onboard the drone.
[2: The Drone Kit] We are still determining what the drone kit should be. Please join our project here to give us some advice on this matter.
[3: Budget Estimation]
- Arduino Uno: already have✔
- Arduino Bluetooth Module: $5.00
- Tiny Duino Game Kit: already have✔
- Tiny Duino Bluetoothe Module: $50.00
- Drone Kit: TBD
- Reel parts: TBD
[4: Next Steps]
- Determine how to replicate what the video is doing above (setting proper “roles” e.g., slave/master for the bluetooth devices.
- Order the parts
- Write code (sketches)
- Order Drone Kit
- Assembly!
[5: Why Join the Project?]
- Learn bluetooth connectivity for Arduino and TinyDuino.
- Meet users with Arduino interests from around the world!
