Product Description:
The scale of the circuit can produce different sounds, while different keys correspond to different scales. The play of the electronic organ is to use the fingers to press different keys to produce different scales. The principle is that the circuit IC555 is connected to an oscillator, whose oscillation frequency is determined by the resistance of the circuit (R1- R10), so different sounds will be generated due to different keys.
This DIY product needs to be soldered and assembled by yourself. If you have any problem or question about it, please leave message to us.

No funciona muy bien, las notas son muy diferentes de como deberían ser.
