I want to make a led art, that everytime a button is pressed it sounds like a heart and blinks a red led with it? Answered


The puslating led I can manage with a 555, but don´t know how to make the sound part.

The smaller the better. Yeah I know I´m noob at this, but thanks for any help?

Buy a "record - a - message" type GREETINGCARD. Record the sound of a heartbeat. Put an LED diode in series with the speaker. that might work but I don't promise it will.
