Re: Will Pay for Help Need Design


Hi, Just to sense the impact and pressure we can use the
strainguage in the bridge circuit and for the display we can very
well use LM3914. Calibrating the sensor would be a tricky issue in
my view. The whole circuit will not cost more than $30.00 best of
luck.

I've been reading a lot of articles online and books but can;t seem to
pull off what i need. So i figure i will just pay someone to do it for
me. It actually pretty simple.

I need to be able to sense the impact/pressure being exerted, and
light a corresponding LED. I would like to have 3 LED colors and
display a different color depending on how much pressure is being
exerted.

For example if there is a high impact a red LED will be lit, Medium-
blue and Low-white. I would prefer to use a Microcontroller so that i
can add features later on and be able to edit the amount of pressure
needed to trigger each LED.

I'm thinking between $100-$200 let me know if you are interested. Also
any input you may have will be appreciated.

Thanks in advance.
