Thanks, CrossRoads!
A few comments:
- I'm sorry if I was not clear in my first post. My plan is to power the Arduino with just one Li-Po battery, and power the two servos from the Arduino 5V pin - which seems to provide up to 800mA (even though I could not find this information in the product page).
- It seems I can use a Pololu Pushbutton Power Switch SV (or LV) for a nice auto shutoff solution!
- If I use a 2S (7.4V) OR a 3S (11.1V) Li-po battery, I won't need a step-down converter, and to measure the voltage I could use a 10K ohm, 1/8 watt potentiometer for a voltage divider and scale the value read from the ADC by software (so I can monitor it).
Does this sound right?
