Infrared Transmitter by IC LM324
This be make a noise light way or Infrared Transmitter circuit by use IC LM324. For enlarge a signal sends the way LED modify the sound to the light or make a noise light way LED there.
I uses the microphone model dynamics at input circuit part takes use op-amp circuit and poto transistor. Fine , R3 , give get sound best quality and if want to send the power as a result fine R5 get down be 50 ohm or lower. Until make LED use current tall arrive at 30mA.
