Insect Repellent circuit diagram

This insect repellent circuit can be placed inside or outside the home (for speakers). If you want to put the whole circuit on the outside of the house, make sure the circuit is in a safe place, especially when it rains.

This circuitry consists of a PLL (Phase Looked Loop) oscillator circuit using a CMOS 4047 with a frequency of 22 KHz. Current drain is around 120mA. So, external power supply is recommended for better results.
