Cmos Oscillator With Music Box Circuit
Before drawing a picture with music box and tapping the LM386 NE555 music do I shared this very nice application and similar projects in the writings of the author of the first version of the circuit is very nice work, especially a great boxing made him the music box CD4017 and based on cmos integrated circuits CD4093 audio signal is given out if the speaker on a variety of rhythm is set up with LM386 gradients with music being made.
