Battery life indicator for Arduino powered fish feeder
So I am basically a noob in electronics and a 1st time arduino user for my project.
I need to do an automatic fish feeder and this is what I have in mind:
I'm gonna use an arduino UNO R3 to connect it to these following components:
- a 16 x 2 LCD Display (connected to RTC chip)
- a small DC motor
- 2 pushbuttons
So these are the main components and I need the arduino to be portable ( So has to be battery powered - Maybe a 9V batt)
As such I have 2 questions:
1) Is it possible for ALL the components to run using power from arduino?
2) I need to add a battery life indicator as well.. how do I go abt doing it?
Hope you guys could help me
