Description

I'd need small electronic scales constructed
It would be good if it can show weight but it is not necessary.
What I need is:

When weight on scales increase a little (by drop of water) it will make short electronic sound.
So if 10 drops of water drop on the scale with 10sec interval, for example, it will make 10 sounds

Thank you

This can be done with a very simple circuit that will use an amplifier to derivate the signal from the weight sensor. To tune it correctly, I need to know the specs of the sensor if you already have it.
