HI WORLD,
actually i am building a Frequency counter, i did almost finish it, now i want a sound system to be added to it,. the fuction of it will be to indicate when a certain frequency is reached but i do not know which kind of circuit and how to connect to it. well i want the sound to be operated to ialert the user when the frequecy = 84Hz or above is reached.
it will be even more exciting if this frequicy at which the sound is operted is varied that is if you could set a freq. and at that frequency or above the sound is operted, but that will require more complicated circuit, which i will do later but if it is also easy then may be i'll do it now. what do you think.
can any one help
P.S. i am new to this field so please help from the basics. :?:
