描述

1. Circuit working principle: Resistors R2 R9 are used to select the oscillation frequency, which, together with resistor R1, capacitor C2, and IC555, generate eight different oscillation frequencies. 2. This musical scale circuit can produce different tones, with different pitches corresponding to different scales. When playing an electronic piano, pressing different keys with the fingers generates different musical scales. 3. The principle is that the IC555 circuit is connected to an oscillator, whose oscillation frequency is determined by the resistance of the circuit resistors (R2 R9), producing different tones with varying pitches.
