Hi there,
I have built a digital alarm (from my last posting 'Schmitt Trigger for counting the time'), and an acquaintance of mine has asked me if I could build an alarm like this for her. But she'd need it powered from a battery, for mobile use.
Now a few questions: Is it realistic to use an Atmega16 for a battery powered application? The datasheet specifies the power consumption for the atmega16l to be 1.1mA when fully powered up.
Which type of battery (of course, rechargable) would be appropriate? I thought of simple NimH batteries, which could be recharged directly in the alarm if an external power supply is connected.
Thanks for any help!
