Guidance needed to implement rate of change of water level

[DaveX]

@strangegk

the idea is to get readings from an ultrasonic sensor and use the millisec or microsec function to get the initial and final timings of the data and process the value accordingly (change in height/time taken). But I am not sure it will work..

Sounds like it will work. If you record initialTiming, finalTiming, initialReading, and finalReading, periodically, it should work.

Do you know how to use millis() or micros() to do a thing periodically? These are all good:

• Planning and Implementing an Arduino Program by @Robin2-- A great way to plan your program to be flexible, easy to read, understand, maintain, and extend. ( Live Sim: Lesson A ... Lesson G )
• Demonstration code for several things at the same time by @Robin2-- An example running a couple blinking LEDS, a button and two servos, all independently. (Live Simulation)
• Flashing multiple LEDs at the same time (thread by @PerryBebbington & others) -- several different styles of blinking leds. These are a collection of some natural extensions to the Blink.ino and BlinkWithoutDelay.ino . There's more than one way to do it. (And if you can blink LEDs, you can run a motor, trigger a device, or do many other tasks) Also, these multiple ways of doing the same thing task might help folks understand the important concepts behind the often-recommended BWOD example.
