In this section we talk about a type of insect repellent insect repellent is a circuit that repel insects from your home or garden effectively. This circuit uses the frequency of bullying of insects to the insect goes. For this insect repellent skesta be installed inside or outside the home can / the speakers. This series of in-circuit PLL oscillator circuit adl / phase looked loop by using a CMOS 4047 at a rate 22 khz.gunakan external power supply for best results.
IC 4047 Description
The CD4047B is capable of operating in either a monostable or astable. It requires an external capacitor (between pins 1 and 3) and an external resistor (between pins 2 and 3) to determine the output pulse width in the monostable mode and the output frequency in astable mode
