When there is a beam, the microcomputer reads the voltage of the photosensitive resistor, which is low level. When there is no irradiation, the microcomputer reads the voltage of the photosensitive resistor, then it is high level. Thus, when shielding the light, can produce the effect of the switch in the circuit. The audible frequency of the human ear is 20Hz to 20kHz, and the frequency of harp notes should be in this range. Its just that different notes have their own fixed frequencies. The can be generated by the 16-bit timer that comes with the 52 single chip. For example, the standard pronunciation of the harp is 440Hz. By calculation, its half period is 1136 s. In this for , the square of 440Hz can be generated as long as the jump pin level in the half cycle. After the electroacoustic conversion component (speaker), you can produce the standard sound la, and the other notes are created as well.

Vintage NOS Monarch MC-24 Microphone. Little Walter Blues Harp Mic. Ladies and gentlemen, this IS the holy grail of vintage harmonica microphones. Let me introduce to you the identical mic that little Walter, yes, Little Walter used in the 60’s. You really can’t find these, certainly not boxed and unopened; it still even has it cellophane on! Only opened to be checked and working. The element in these mics are pretty good with a strong signal There are very few pictures of Walter holding a mic, hence the mystique as to how he got his sound. Out of these few pictures this is the only this mic that is distinguishable and has become known as the Little Walter mcirophone. Feel free to check this fact out. So original is this mic it doesn’t have the jack plug fitted, this is how it will be sold , 100% original. Due to the age the on/off switch isnt working but perhaps with some contact cleaner it can work again. Geab yourself a piece of blues history.
