This time, we attached the circuit into our cardboard prototype.
We did write the codes, but they didn’t work the way we wanted to, so for the presentation, we just tested out the sensitivity of the photoresistors. At first I was a bit worried that the photoresistors wouldn’t be a very good sensor, but they turned out to be more sensitive than I expected.
Feedback received from the presentation:
- Use backlight instead of LEDs on the gap so it won’t interfere with the photoresistors
- Add ambience noise (e.g. whispers) to attract audience
- Play around with the volume
So now, the things that we need to focus on are:
- Think of the materials we need and the exact amount of each of those
- Start making the story: think of how many recordings to make and the length for each one
- Settle the code
Video of the class presentation:
After that, I went back and tried to fix the code. We need to make a circuit where when the light that falls on the photoresistors is on the minimum (darkest), the sound will start playing. Since we don’t have ethernet shield to read SD card (is that what we need?), for now the sounds are just from the buzzer. Here’s the working circuit.
However, I’m still not sure whether we need the sounds to overlap each other when both of them are triggered or not, but for now there will only be one sound played regardless of the number of sensors activated.
As for now, I think we’ll need to just try the different things first and make sure the electrical component works.
