The physical remote device called a clicker can be replaced with an application or program that can be installed on smartphones, while the polls are created through the website. In this research, the Audience response system was built using Node.js, PhoneGap platform, and the WebSocket Socket.IO as Javascript library to support bi-directional data communications. Based on testing result, this application can run properly all the functionalities that have been mentioned such as login to the system, create a poll, join a poll, and give a vote.
