imer IC tachometer and other projects in the large number of applications. The IC is wired shooting mode to the mono a fixed pulse width, PWM frequency of the input signal of variable frequency. Resistor R4 and capacitor C2 provide the necessary timing circuitry. In the form of transistor T1 parallel to the C2 discharge path it is necessary to re-trigger the IC. Capacitor C1 as the input DC isolator. Schematic Precautions The circuit board assembly in Verona. A 12V DC power supply circuit. LM555 must be installed in the holder. The output of this circuit is not a pure DC, but the PWM waveform. Additional circuits require pure DC converter PWM waveform.
