This melody organ circuit generates 25 different tones by touching the conductive electrodes with the metal probe. The tones range from low to high. A great project to learn electronic assembly
This mini organ circuit generates 13 different tones by touching the conductive electrodes (A-M) with the metal probe. Conductive electrode “A” generates the lowest frequency...
Make a sharp sound and the circuit will produce barking dog
alarm. FK279 can be also used for controlling the operation
of other sound circuits. The sound IC can also be changed
with other FK200 sounds(see details). Ideal for toys and
advertising.
A sound generating circuit that uses the digital memory principle for
creating a 6 car alarm type sounds. Ideally, the circuit is suitable
for fixing to a small toy car.
