Arduino Mega prototype analog timer interrupts: newbie question

Question

I am currently using an Arduino Mega with a fast vibration sensor to trigger the components operation (force sensor, temperature sensor) and also toggle sleep mode.

I am very new at this and I have been doing some googling, but I just can't seem to understand it.

So, my questions are:

1. How would I toggle(on/off) sleep mode?
2. How would I use interrupts (timer, pin change interrupt?) for an analog pin that triggers when the vibration sensor is triggered, resulting in other components operating?

I am currently working on a Mega, but I will eventually move on to the Arduino Mini Pro. I hope there are no exclusive problems later on.

I realize that this is not a professional question, but I find these tasks very challenging.

Please help me. An example link or perhaps example code to help me understand better.

Thank you very much.

Thee best and most authoritative answer to that and all your other questions about the chip can be found in thee device data sheet and the compiler manual. Read them thoroughly and then write code to the data sheet to experiment.

Your can fire example have an analog interrupt where the chip constantly does ADC on the pin attached to the sensor and you can test the value of the ADC to see if certain trigger conditions are met and take appropriate actions.

The same with timers, etc. The data sheet is your best friend.
