Hello everybody,

I'm a new programmer in ARDUINO platform. I need a help.
I'm using HC-SR04 to find the distance.
In my system distance is may vary.
For example it may vary toward 1cm to 15cm, or 15cm to 1cm.
But I want to save only the data when value is increasing from low to high.
When it goes from high to low, then it will remain showing highest value. It'll not show the new lower value.
Please please please help.

Start your own thread and ask your questions in it.
Always show us what code you have and attach an image of your circuit.
