About this item

• POWER SUPPLY VOLTAGE: DC3-12V. PCB SIZE: Length 13.5CM* width 2.2CM.
• It is simple and practical, and the power consumption is small, and the circuit is driven by an integrated circuit. The parts are few, and the line is simple and clear
• The scales of this circuit can produce different sounds, and different keys correspond to different scales.
• The way of playing the electronic organ is to press different keys with your fingers to generate different scales.
• The reason is that the circuit IC555 is connected as an oscillator, and its oscillation frequency is determined by the circuit's electrical power. The resistance (R1-R10) is determined by the resistance value, so different buttons will produce different sounds.
