[Background] I'm constructing a water bottle rocket which is going to use apogee detection and a mechanism for the parachute release.
Connected to the Uno will be an accelerometer and a servo, now due to the need to minimise the dry mass of the rocket I want to use as few and as light batteries as feasible. Would it be possible to power this setup with 2 AAAs? If not how many would be necessary? Would other types of Arduino such as a micro work on fewer batteries?
Thanks for the help
