Pulse generator circuit shown in the schematic diagram below produces square wave pulse with adjustable duty cycle/active factor. The benefits of using this circuit are low components count and high stability of its output frequency. The frequency of this pulse generator is fixed, the frequency f depends on the value of R and C1, following the formula of f=1/(1.1*R1*C1), where […]

Tone/frequency 567 decoder IC (integrated circuit) is not only produce an accurate oscillation, but also delivering a good current handling capability. Up to 100 mA will be safely driven by this single chip oscillator, this means that you don’t need any buffering for most small application. With 100mA, you can drive a small bulb, relay, buzzer, or many other devices. […]
