To Use This Sample App…¶ ↑

1. Install the latest version of the Arduino software from arduino.cc/en/Main/Software.

2. Plug up an Arduino with an ATMega3328P processor, with an LED on pin 13 (and Ground pin), over usb.

3. Change your port name in config/hardware.yml

To match the port of the serial device on your arduino board (can be found in the Arduino software menu Tools>Serial Port)

1. At the command line, run bundle install and rails s

2. Go to localhost:3000/ in your browser and you’ll see two buttons you can click to turn the LED on and off.

Notes¶ ↑

This app uses rake to compile arduino sketches and write them to the arduino in the background based on a trigger in a rails app (i.e., a button click). If you are looking for a tighter, ruby language integration with the arduino, check out the Dino gem.
