32 LED Stereo VU Meter with PIC

Post by [eDo] »

Pozdrav drugari! Nije bilo novotarija u skorije vreme pa da malo ubijemo monotomiju :) Stereo VU metar sa 32 ledice jedan PIC 16F88I/P neshto malo delova i eto projekta. Ovaj VU metar mi se vishe svidja od onih sa LM3915 ovaj ima 16 dioda po kanalu i neshto najlepshe ima peak memoriju. Takodje ima i jumper-e za dodatna podeshavanja ali o tome cemo u klipu koji cu sutra snimiti i postaviti.

Evo mog videa.

Radi super samo je malo struja preslaba za normalne LED, trebalo bi staviti tranzistore.
Projekt je rađen za 2 mA ledice.
Don't turn it on - take it apart!

Smanji otpornike od330 na 180 -150 oma...Za 20mA diode se stavljaju 22R optornici....Danas cu i ja da okachim video ali u svkom slucaju mnogo lepshe nego sa LM3915 :) P0zdrav dobar video :)

Probao sam mjenjati otpornike od 20-330 ohma ništa se ne mjenja.
Ako stavim ove Ultra Bright LEDice onda neke svjetle jače a neke slabije.
A s običnim 5mm ledicama ne svjetli ni upola tako kao sa lm3914 ili uaa180.

Također sam ubacio 1kohm otpornik +PNP tranzistore na izlaze iz pica koji vode na zajedničku anodu ali
onda cijeli sklop poludi i diode svjetle bezveze.
