Velleman sound-to-light kit
I would like to connect this board directly to the headphone (output) jack of my audio device (metal detector), thereby bypassing the microphone input. This would allow visual operation of the detector without the use of headphones. When an object is detected it would illuminate an LED as opposed to sending an audio signal.
Is it possible to de-solder the microphone on the circuit board and solder in a 3.5mm male connector which would plug directly into the audio output device?
I have never worked on a circuit board before and I have ZERO knowledge of electronics, but the kit is only $8 - so I think it's worth a try - if the electronic wizardry is correct, that is.
Thanks in advance for any help!
