I am trying to build a small robot based on the arduino Uno.
There are going to be 4 motors and i would like some power source recommandation.
- 3 DC Motors which work with either ≤200mA at 6V or ≤150mA at 3V
- 1 DC Motor which work with < 500 mA at 3.7V
- One Arduino Uno with around 5 v and 40 mA
Can you recommand me a rechargeable Power Supply for this kind of project? I was planning to buy a 9v rechargeable battery with 1A.
