This is the schematic diagram of Western music generator circuit based on single IC HT82207. This circuit is able to take you towards the world of the Wild West. The western music already programmed in the chip. It utilizes the integrated 18-pin HT82207 (IC1) of Holtek, which literally takes care of almost everything.
You’ve to do is add several accessories, which includes a loudspeaker and six selector switches. From an operational point of view, HT82207 hosts inside a generator noise sequences, that listening to them. Reminiscent of the Wild West. The variety of sound is via the switch S1-S6. Within the resting state, the circuit absorbs power less than 1mA.
