Mosquito Repellent Circuit. On the one hand the transmitter is fed directly from the us2 generator output to construction that i used the 555. It can be used in any kind of setups such as homes offices hospitals to protect people.
Which the signal of this circuit is determined by both resistors r2 r3 and both capacitors c1 c2. A multivibrator is an electronic circuit which is used to generate a pulsed output signal. The sound frequencies get out of a collector of q2.
Therefore appropriate is required control.
A multivibrator is an electronic circuit which is used to generate a pulsed output signal. Components required 555 timer an electrolyte capacitor of 0 01 micro farad a ceramic capacitor of 0 01 micro farad a resistor of 760 ohms another resistor of 1 5 k piezo buzzer a spst switch a 5 v battery. So here we are going to design a simple mosquito repellent circuit which will be producing a sound of approximately 40 khz. Therefore appropriate is required control.
