Hi,
This is my first post in the forum, hoping someone could give me suggestions on our group project.
The project specifies that we use LM3915, not for its common use like VU meter, but for other creative purpose. And I was lucky enough to convince our professor on this "easier" project, compare to the other group.:grin:
We came upon with the idea of using the 10 output of this IC for displaying ten levels of the commonly known arcade punch machine, and we intend to use a vibration sensor or piezoelectric sensor to absorb the punch and convert it to signal and be fed on the LM3915. That's the rough idea of it but the details is still in the limbo.
Could someone give me an idea on how much power a punch can generate or the power of the max signal we need to divide for each of the ten level.
Any suggestion is greatly appreciated!:thumbsup:
P.S. I just remember we also got another project in another subject in which we need to make a toy car turn left or right, either is fine it just need to turn, after each clap. We already got the idea of clap switch and the use of a twin motor gearbox but we haven't got the solution as to what relay we need to use to make one motor stop while the other continuously run to make it turn. Please do name the relay that could make this possible. Thanks!
