【正文】 解決方案：將電位器RW11換成1K。調(diào)節(jié)對(duì)應(yīng)的電位器，得到所當(dāng),按下S8，時(shí)，調(diào)節(jié)RW8,使555的3腳輸出的頻率為523. R=RW8。 關(guān)鍵字：NE555 多諧振蕩 RC充放電 音量 節(jié)拍Summary:555 time base circuit as the core constitute more harmonic oscillation circuit, through the control keys on/off to change the output frequency, so as to when each time you press a key, sound one note the horns. Designed to be simple, easy to implement, and performance for volume and tempo can be adjusted to meet your performance needs. Keywords: NE555 beats harmonic oscillator RCdischarge volume目錄1. 系統(tǒng)設(shè)計(jì) 4 4[1] 4 42. 單元電路設(shè)計(jì) 4 5[2] 5 5 5 5 6 節(jié)拍發(fā)生電路 6 6 6 6 6 7 7 7 7 84結(jié)果分析 9 10 11 12 12 12 13 14
