Information!

hello,
I call you from Athens.
I'm not profesional at electronics, so I address you.
I would like to build a construction in an area which will be led by strong ligit flashing depending on the music and completely closed when not playing music.
I would love your technical knowledge to succeed and what will need from your products.

I'm looking forward to answer me soon,
Thanks a lot!

read #6 carefully.

I have to assume that English is not your first language. Well done on learning enough to talk to us and welcome to the group.

are you looking for a device that will flash lights when music is played ?

buy :
an UNO
a microphone
resistors : 220 ohm , 470 ohm , 330 ohm , 1,000 ohm, resistors
some 2n7000 FET (3 legs) (10 to get started)
a proto board
many different color LED's

when the microphone detects music, you can make a program that will make the lights come on and off.
