This was a fun project which integrated Android, Arduino, 3d printing, mechanical and electrical components on the trailer. The 3d printed model was for showing the concept and practicing operation and coding at my desk. Then the full size trailer was outfitted with lights, air speed sensor, and the Arduino 101 board. The Arduino communicated with my phone mounted on my handlebars and displayed info on the app I wrote for it.
