First time using KiCAD and need help in making sure that my schematic is ok. I’m using an Arduino Nano for my project.
The pic is the whole setup. I’m planning on using a battery but don’t know what type of symbol to use or even where to connect.
Battery and Battery_Cell are found under Device, or enter Battery in the search box.
Tip: Good practice is for schematics to be drawn with GND going down and +5V going up. You can flip the Nano symbol about the X-axis but you’ll have to flip the wiring around it too. Good editing practice for you.

The buzzer is also in Device. The Servo is in Motor.
If you don’t want to do a lot of editing of wires, you could highlight the whole schematic and Mirror Vertically.
I don’t know if Kicad has the 16 push button array.

Thanks for the help, where do I connect the battery to the Arduino Nano? On the VIN pin?
Thanks for the help, I’m planning to use the pins and sockets to connect the parts since they have connectors or am I wrong in doing that and have to use the ones you mentioned?
The negative pole of the battery to the GND pin and the positive pole to the +5V pin. You might have difficulty finding a battery of exactly 5V. Depending on your application you might need to decide on an appropriate number of cells to get close to the desired voltage.
We also know nothing about the buzzer and the servo. However please do not supply those details because this gets into circuit design which is not the focus of this forum; we have to concentrate on usage of KiCad. You should probably take that kind of question to an Arduino forum.

Another question, can I just use a 01x02 pin connector for the battery? I won’t embed the battery unto the PCB. Like I’m just gonna solder their connections.
We have no idea what kind of battery you intend to use and what connectors are attached to it. It’s not a KiCad question.

I see, thanks again for the help. Guess imma have to go to other forums.

Normal procedure is if the parts are mounted on the board, you connect them with wires. If the parts are not mounted on the board, you place a socket on the board and a plug nearby that is connected to the off board part.
So, you will have for example:
Arduino-wire-socket called S1, then space, then plug P1-wire-Buzzer. The off-board components P1-wire-buzzer are marked as not on the board, but drawing a schematic this way allows the reader to understand where S1 goes.
It is best if you surf the net to find out how and why schematics are drawn, and how to layout them.
When you understand how schematics are laid out, if you have questions about the use of Kicad, please ask here.
