Hi guys, here's what I'm looking to do. My team is working on an installation piece for Burning Man 2019 and one idea is to create an amplified footstep in the desert.
I'd like to rig a pressure plate (using velostat or a similar pressure responsive conductive material) to trigger a sound linked to a subwoofer buried in a box beneath the sand, in effect "amplifying"each footstep. I'd be using a 400w powered sub potentially so I know quite a bit of conversion would be needed.
I'm totally new to the arduino world so any advice would be greatly appreciated!
I assume you are going to play a pre-recorded sound, not literally amplify the footstep?
There are various "audio shields" that can play sounds triggered/controlled by an Arduino, or otherwise triggered. You may not need a microcontroller, especially if the sensor isn't analog.
Yes, it would be a pre-recorded sound, although the actual footstep amplification could be cool!
So the audio shield would contain the recording? You're saying you wouldn't need the Arduino unit if the sensor isn't analog? Could you point me to a proper audio shield? Sorry I'm totally new to this!
