hello sir
i ve two relays in a oscillator circuit of my own purpose but i want to replace relay with an electronic circuit using transistors etc etc , i tried with some practicals but i am getting the amplified output of what i am feding to the unit , i want exact funtion of relay as like 2 way switching as we get in case of relay . . please help . . thankssssssssss
sir very frankly speaking i ve a motor speed controller PWM circuit & its general as available on net . Now the story is i want to fed this input to the motor randomly by interchanging polarity , thats why using two relayys for the purpose but as its a mechanical part so less speed & high power required & so many chances of damage . Moreover creating "tick tick" sound the irritating one . . now i guess i explained what i need . . now please help me sir . . thanks :-o
sir i am searching for L293d but unable to find one so help me to get a better option , i found an electronic relay function best here , please help me to make that or if you have any suggestion please proceed
