DIY NE555 Multichannel Waveform Generator Kit Electronic System Training Starter Kits

Description: C7 is a filter capacitor in the circuit. U1, R1, R2, C2 constitute a square wave generator, the signal is output from U1's three feet, C1 is anti-interference capacitor. Square wave output from the third leg of U1 is coupled by R3, R4 partial voltage and C5. Square wave can be output at the output end by short circuit block connecting J1. The other way is through C4 coupling and C3 partial voltage, through integration circuit R9, C6 to form sawtooth waveform output by J2, and then through the next integration circuit R10, C8. Form triangular wave output from J3. Finally, after the amplification circuit composed of C9, R5, Q1 and R6, the Q1 collector becomes a sinusoidal wave. R7, R8 and Q2 constitute the emitter following amplifier circuit. Finally, the signal is separated by C10 coupling R12 voltage and output from the output terminal. R12 can be used to adjust the output amplitude. NE555 multi-channel waveform generator can generate square wave, sawtooth wave, triangle wave and sine wave. By choosing a waveform output through jumper, the circuit is simple and the operation is convenient.
