NE555 multi-channel waveform generator electronic production kit training parts.
Supply voltage: 6-12V DC voltage, 9V is recommended
Product manual:
NE555 multi-channel waveform generator can generate square wave, sawtooth wave, triangle wave, sine wave.
A waveform output is selected by a jumper, and the circuit is simple and convenient to operate.
In the circuit, D1 is an anti-power supply diode and C1 is a filter capacitor. IC1, R1, R2, and C2 form a square wave generator, and the signal is output from pin 3 of IC1, and C3 is an anti-interference capacitor. The square wave output from the third pin of IC1 is divided by R3, R4, and C5. The short-circuit block is shorted to J1 to output a square wave at the output. The other way is divided by C4 and C3, and the sawtooth waveform is formed by J2 through the integrating circuit R5 and C7, and then the next stage integrating circuit R6 and C8 form a triangular wave to output from J3. After the final R7, after the amplification circuit composed of C9, R8, Q2, and R9 is amplified, the collector of Q2 becomes a sine wave. R10, R11, and Q1 form an emitter follower amplifier circuit, and the final signal is divided by W1 and coupled to W1, and output from the output terminal.
