Later I will show how to add a microphone to it so it is wireless.
I have a project with 20 LEDs in a bar-graph. It is sensitive enough to indicate a pin dropping on the floor on the other side of a room. It has a microphone and a rechargable battery. It flashes to the beat really well.
What details? My circuit here is just a little power amp IC with DC biasing so that its output voltage without a signal is zero, and a rectifier followed by a pulse-stretching capacitor.headcracker said:hey audioguru
can u furnish some details abt ur project......me trying to create a led network controlled by music (like music lights) for a project.....
i mean it wud be a light decoration kind of a thing which wud vary light intensityaccording to the intensity of sound
i read ur posts and thought that ur project wud be really helpful in mine
The input of the LM386 can be connected to either channel's output and work fine. Maybe you connected the input of the LM386 to one channel's output and the ground of the LM386 to the other channel's output.ferrari99 said:im testing it on my mp3 player and put a splitter in the headphone jack so i could connect my headphones and also see the LED working to the music. When i connected the LED a first nothing happened until i shorted the left and right audio output to go into the audio input of the device. If i do that then i can only hear from one ear of the headphones.
The gain of the LM386 can be increased 10 times by adding a 10uF capacitor between its pin 1 and pin 8, positive at pin 1. The headphones should work fine if everything is connected correctly.I guess the LED needs a stronger input. Is there a way of getting a stronger input and also being able to listen through my headphones?
A 22k resistor from the L channel and a 22k resistor from the R channel and their junction has a 560 ohm resistor to ground and is the input to the circuit. Then the level is reduced to about 1/20th.And also, since im preparing this for a stereo, and since stereos have a much higher output than small devices, how will i be able to take an output from the stereo and adapt it to the right input for this device.
It is accidental, all right!catcat said:EUREKA!
(this is an accidental invention.)
It follows the music, sometimes.ballpoint said:He had a video of it working on there though.. you're saying it wont work at all?
