Brief Overview

This consists of a furniture, an L shaped bench which allows two people sit near each other without forcing them sit next to each other. If one person sits on bench, a music starts playing and if the other person also does the same, two audios start playing in sync and will create a soothing experience for their ear. This makes them curious and will be a baby step towards starting a conversation between two strangers.

Challenges faced :

1. We planned to do the final model in real size with the help of CNC Router (Big) in makerspace. But 'Press fit' was found to be difficult with the machine since the corners were rounded after cut, so that measurements of the whole model had to be changed.

2. Arduino Coding for the music sync was a struggle since we couldn't achieve the result without any delay. We tried a simple program with delay of 4.4 seconds. Even though it was working fine, sometimes the delay was a hindrance to smooth playback of the audio.

Arduino code for the program is given below.

3. Since the FSR sensor used for the program was not so accurate, sometimes it read random values because of the residual pressure, which resulted in audio playback randomly at unexpected times.

4. Since only one pressure sensor is used on one seat, we had to give pressure accordingly so that it can detect.

5. Only wav files (mono, 16kHz, 8 bit) can be used in SD card module connected to arduino. So the audio quality is low.
