As my very first arduino project, I’m trying to build a mini sumo robot. I have almost all the components I need but there are a couple of questions regarding to L298N powering.
These are the components I’m using:
- Arduino UNO board
- Zumo chassis
- Sharp IR sensor
- QRT reflectance sensors
- L298N motor shield
- 2 DC motors
- 2 IR sensors
Now about powering. I’m thinking of using a LiPo battery but I have the following questions:
- My first though was to power the L298N, with the 5V jumper on and using the 5V out to power the arduino. I know the motor shield has a 5V voltage regulator but, is it a good idea to use it?
- About the previous question, I also would like to know which is the best pin to connect the L298N to the arduino board, L298N-5V-out → Arduino-5V-in or L298N-5V-out → Arduino-VIN?
- If none of the previous options are recommended, should I use two separate batteries?
- Related to any of the final solutions, which LiPo battery would you recommend?
I know there are too many questions, but I’m new in this world and I don’t want to ruin any board with a bad powering setup.
Thanks in advance.
Any information you’ll need just ask me.
