i ordered a Sparkfun Sound Detector because of the binary gate.
What I'm trying to do:
1. I want to have the binary gate emit light from a 1 watt LED, when it picks up sound.
My Problems:
1. By default (not connected to microcontroller), the sound detector turns on the LED light and keeps it on until it picks up a sound, causing an interrupt. I'd like to have the light stay off and emit light when sound is picked up. (The opposite of what it is doing now)
*Do i have a defective product?
*Can I change this on my Arduino?
2. When the light is being emitted, it's not at it's highest potential. It's really dim compared to connecting the led to ground + 100k resistor circuit.
Any help would be appreciated. I am new to electronics, so feel free to talk to me like I'm a 3 year old.
Thanks.
