Hiiii…..friends now its time for another basic electronic
project for beginners. This time I am
going to show you a simple tone generator circuit using NE 555 IC. In this project
we will see how we can generate a pleasant melody by using some basic electronic
componentS.
CIRCUIT DIAGRAM
In this circuit NE555 IC is used in astable mode(free
running mode). In this circuit a variable resistor is also provide by which we
can control the pitch of tone generated and we can get multiple tones by this
single circuit. The capacitor is provided to reduce the noise interference and
getting a smooth pitch sound on adjusting.
Want more detail about NE555 just go through the DATASHEET OF 555 TIMER IC
I hope this project was an interesting one, in case of any
doubt leave a comment.
THNX..:)
