how to make simple 700hz oscillator for synthesiser?
hi there, i want to make a warning beeper for my car, and the current buzzers dont do it for me. so i want to make my own tone maker, to make the tone.
i think it can be done by attaching an oscillator to a speaker and battery. how do i create this ? any help apreciated 10 pts!
There are manufacturers Application notes for various ICs & Transistors
the simple one (just my opinion here) is a 555 timer with the time constant set to produce a 700hz tone, the output will be square waves but you can filter it for whatever you want.
the circuits can be found on-line, "555 application notes"
Enjoy
& Good Luck
