Cute johnny-five quadbot controlled by a nunchuk.
git clone https://github.com/codealchemist/quii
cd quii
npm install
npm start
Commands from the nunchuk are sent to the quadbot to control its movement.
A quadbot and a nunchuk connected to their own Arduino boards. Both with firmata installed. You will also need to customize your board ports.
Once you have that working this is super fun! :D
