Circuit Diagram issue

[ibunny30]

hi,
I am making a RC car using arduino also new to this forum. So, my issue is in remote control part of rc car. I am using arduino nano, NRF24L01, 2 joysticks and a 9v battery for this. I am a bit confused in circuit schematic diagram as i am new to arduino nano so need help in it.
will be very grateful for the help.
thank you
regards

A schematic is a type of circuit diagram. But it does not necessarily accurately represent the physical size, orientation or position of the components, only the connections between them. Even the physical layout of the pins of a component are not necessarily accurately represented. This means the components and their pins can be positioned and oriented in what ever way makes the diagram clearer and easier to understand, with fewer criss-crossing wires.

A schematic should always label each pin with it's function (not physical pin numbers), and show component values and part numbers.

Hope this helps.

@ibunny30

and a 9v battery

This type of battery is not suitable for your project. I suggest you switch to 4xAA NiMH and power the Nano through the 5V pin.

How are you powering the NRF2401? The 3.3V pin of the Nano cannot provide much current.

hi paul,
actually i am new to arduino nano so confused about the pin points and attaching nrf and 2 joysticks to which pins

[ibunny30]

i am using a voltage regulator for the nrf

[PaulRB]

You said you were confused about schematics, so I tried to explain their purpose. Did that help? Are you less confused about what a schematic is?

[ibunny30]

about schematic i got it but the pin points i am confused actually

Is this related to

Arduino based racing car problems

So I am designing and developing an Arduino-based racing car equipped with a robust suspension system, gears for efficient power transmission and stability, and a NRF module for remote control and telemetry. But for the schematic diagram of the circuits for the car i am confused of where to use resistors and capacitors of what values and also my circuit is correct or not please help... components I use are : arduino uno r3 servo OT90MR 2 lithium ion polymer batteries>11.1V2200mAh3C L298N Mo…

[ibunny30]

yep

[jim-p]

So if you figured out how to do that, you should be able to figure out how to do this, it's similar.

pin points of arduino nano i am confused

[jim-p]

You are still confused?
You said you are no longer confused?

Hi, @ibunny30

@ibunny30

pin points of arduino nano i am confused

Please post the schematic you are following?

Have you got a diagram of Nano pinouts?

Tom...

[ibunny30]

Thank you very much Tom that's what i was asking.

You can get all the info you need on your arduino board through arduino. If you look up something like:

Nano Arduino docs

You will get documentation for the datasheet, pinouts and schematics.

Just try use the documentation that is available. Same goes for using libraries. Use the documentation and it will save you a lot of time and headache!
