Hi
I think a simple LM3915 or 3916 could do most of the job, offering moreover a superb "christmas tree " ... to your child's eyes.
just select the open collector output for the level to trigger!!!
National datas offer the drawings for full wave rectification, averaging, peak detection ... Heaven !!!
No, Analog circuits are not dead ...

That's for sure, return to basic, it's still a good pratice. Let`s seeOriginally Posted by Acetronics
- PIC 12F629 => 2,28$ each in really small Qty will fit in half of matchbox
- LM3914,LM3915,LM3916 => 3,15 - 3,75$ + external capacitors, extra board space + chances to do some erratic turn off when signal is a bit low, and blah blah blah
j't'emerde... c une farce... humour Québécois
Is the score is still the same... BAH who cares!!!
Mes amitiés à la France!

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

Hi, steve
I've paid my LM 3915 1.80 Euros ...
If it's a problem for you, a gang of transistors ( 5 to 6 ? ) plus some R and C can fit into a sugar lump ...
I already did that for a sound animated christmas star ... ( 16 Leds, 4 channels !!! )
Here, Relay will have to keep outside ... too bad !!!
But, Why not to use a PIC ???
Cheers to la belle Province !!!
