Musical horn circuit.
Description.
Here is a simple circuit diagram of a simple musical horn using two NE555 ICs.Two ICs are wired as astable mutivibrators.The ouput of first multivibrator is given to the discharge (pin 7) of the second astable multivibrator.The combined effect of the astable multivibrators produce a musical tone at the output.
Circuit diagram with Parts list.
Notes.
- The sound effect can be adjusted by varying the POTs R2&R5.
- The speaker can be a 8 Ohm tweeter.
- The circuit can be powered from a 9V PP3 battery.
- The ICs must be mounted on holders.
- All capacitors must be rated 15V.
very good one ,sir
i m one student of tech in my
anmar ,asia
i interest more on wireless control n robot tech
thank
Can anyone please design a circuit to supply 6v on a clap i.e a clap activated 6v power supply.
6v output should be continues and show proper relay connections
