Rubber band launcher: no droids were harmed!
Jonathan from Anikken wrote us to show how Andee is more than just a Bluetooth shield. Not only does it allow to wirelessly connect and control the Arduino from any Android phone, but it comes with its own library for the Arduino IDE, to easily customise the smartphone user interface by doing the coding in the Arduino IDE itself without any Android programming.
He then created some action with it producing a Rubber band launcher and a cool video to see how it works:
I got the inspiration to build this rubber band launcher after watching a video of a rubber band gattling gun. I originally intended to build a rubber band gattling gun turret that I can control with my smartphone using stuff that I could find in my home and office.
Unfortunately, I didn’t have enough materials lying around to get it done. Instead, using whatever I had, I improvised and made a simpler version – the Rubber Band Launcher Mark I. (I’m calling it Mark I because I’m in the process of upgrading this model).
The launcher was built using some plywood, cardboard, cable ties, some screws, two servos, the Arduino Uno, and the Annikken Andee.
He started with a piece of plywood that he found in his office, he cut it up and mounted two servos to it using screws and cable ties : one servo controls the firing of the rubber band, the other controls the up/down movement. He then mounted the machine onto a cardboard box filled it with heavy objects to prevent the launcher from topping over.
All in all, the total time taken to construct it took less than three hours. Not bad, right? Follow the instructions, check the code and make it yourself here.
