Hi Guys

I am new to this and are in need of assistance. I want to build a low power LED Chaser unit that utulizes sound as input. I have seen a lot of LED Chaser units but not one that operates like a "Sound 2 light" unit.

Any help out there?

Appreciated....

 

Hello, and welcome to the forum!

First question: Are you thinking of a chaser that goes back and forth, or goes form one end to the other then starts back at the first end?

Hello,

What do you want the led chaser doing?
Stepping when there is sound?

Hi, Guys

Thanks for your response. And the answer to your question is yes - it should step based on volume of sound.

Hope this answers your question.

Best,

Always more questions. We do not care about frequency, just advance a count every time volume crosses a threshold??

 

Volume is not gonna do much unless you turn it up yourself or you like commercials.

Step like a light organ? With different frequencies lighting up different colored LED's? I'd like to see that myself! I have made 120 volt ones that used SCR's to run 120 VAC miniature light strings like that.

The circuit used different capacitors with identical coils to trigger the SCR's. In fact I wound the coils around the capacitors. I copied a circuit originally sold by RS as speaker type boxes with medium Christmas bulbs in them. I still have the ones I made, but I have to get new light strings. LED's come in strings of 50, but my old strings had 35.

Is that what you want?
