Informação do fabricante:

This DIY product needs to be soldered and assembled by yourself.

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.

Parameters:

  • Power supply voltage: DC3-12V
  • PCB size: length 13.5CM* width 2.2CM

Features:

  •  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.
  • In the process of debugging, the understanding of the principle of the circuit will be deepened.

Component List:

NO.
