I need some advises for a technical design of an arduino car (2Wheels).
How can I do an approximative calculation for the power supply (2 Electro motors and 1 Arduino Board, 1 Motor Shield, 1 Bluetooth-Module).
Everybody just uses 4x 1,5V Batteries but nobody gives a reason why they are using this one.
I would calculate the power the electro motors need in a sceond but I can not find any details for my calculation.
You can find my chassis with electro motors by following the link:
