Four-tone circuit

Published:2011/5/17 1:12:00 Author:Christina | Keyword: Four-tone

Four-tone circuit
This circuit can send out four kinds of single tones and four kinds of flash effects by using two switches' four different combinations. BG1 and BG2 are the clearance oscillating circuits, you can adjust the oscillation frequency by using W; BG3, BG4 and Y are the audio oscillating circuits, and you can change the tone by changing C. K1-1, K2-1 and K1-2, K2-2 are two switches, when they are 00,01,10,11, the circuit is in four states and can produce four kinds of single tones and flash effects. (View)
