Akachan is a LINE BOT API Trial account that is linked to a Raspberry Pi, speaker and USB web camera.

The web server is written in Node JS which handles communication between LINE and audio server. It should ideally run on a public IP, Heroku (https://dashboard.heroku.com/), or other cloud services to communicate with LINE securely. Audio server is running on Raspberry Pi and communicates with the web server through web socket. Sound detector uses Neil Yager application.
