This Circuit Generates a Frequency From 20-38 KHz. These Range Of Frequency Irritates Mosquito And They Runs Away From Your House. human can't hear this frequency but animals and insects can hear this.
Here we used a 10K variable resistor which is used for increase and decrease the value of frequency.
Components required
Breadboard or brownboard
555 Timer IC
10k variable resistor
1k resistor
0.01uf capacitor
9v battery
jumper wire
buzzer
Notes.
Use 8 pin IC base for 555 timer if design on PCB
Best way to design a circuit is on breadboard
Adjust frequency at on higher value
9v to 12v DC power supply can use
Use all through-hole components
Use all precautions
