On-campus tryout 555 sounder

Overview

This time, Lichuang sponsored the electronic design competition topic. I chose topic A: 555 sound generator. The specific requirement of this project is to use NE555 to complete a sound generator that can controlly emit a total of 8 tones from midrange C (1) to treble C (1). It can be powered by USB or battery. I hope the circuit is as simple as possible and as controllable as possible. As strong as possible, the sound effects are as good as possible and make as much sound as possible. The 555 sound generator that I designed and produced myself is powered by USB. The simulation results have good sound effects and the pitch is close to the standard scale.
