Hardware Recommendation for Newbie

Hi,
I'm currently working on a project and I'm very new to electronics so I'm not sure what product i need. I will outline the project below:
I am making a self driving car. I'm allowed to push the start button only at the start of the test. The car must drive on its own in a straight line 25 feet.
Then stop within 5 feet.
Then the car will need to fire a projectile 10 feet into a target.
I am planning to use a nerf gun for the projectile.
So essentially i need to get a board that i can program to start the motors and run for a specific time, then shut off, then activate a trigger to fire the nerf gun.
Let me know what you think would be best for me

  • Sounds like a simple Arduino UNO would work.

  • An inexpensive geared stepper(s) could drive the wheels.

  • A hobby servo could operate the gun’s trigger.

Welcome to the forum

How straight must the car dive ?

How large will your car be and how large can the battery be? How many wheels on the car and how many will be motor driven?

I will reply in a new comment rather than reply to each question individually.
Attached is a picture of the chassis that I have for the project. I will need to attach the nerf gun, controller, and hobby servo for the trigger mechanism.
The car must drive very straight, but with the chassis i have i dont think it will be an issue.
the car is about 2 feet long and a 1 foot wide.

5 feet of what? When you push the button again? Who is doing the 25 feet measurement?

How do you intend to solve this?

Do you intend to lock the steering and hope the car doesn't drift off course, maybe due to a change in centre of gravity if the battery is positioned slightly differently between tests for example.

Or maybe you are going to implement a line following system and a servo to adjust the direction of the car?

I don't really need advice on all other aspects of the project. I really just need hardware and coding recommendation. The controller will need to communicate with 2 electronic devices, 1 is the DC motors for the wheels, and 2 is a hobby servo for the trigger mechanism.
I will need to program the DC motors to turn on for a specified amount of time, then shut off.
then I need to program the hobby servo to fire the trigger.
That is all the recommendations i need for this project.
thank you

Right now, starting from zero, it doesn't appear that you are in a good position to make that judgement.

And since forum members don't know how the thing shown in the picture is powered or controlled, they are not in a good position to advise you.

Have a look at the "How to get the best out of this forum" post, which will give you some ideas about how the forum works.

More Stone Soup...

... nothing more, but...

That is all? Have you considered reading, learning and putting in some work, and not asking for a hand-out?

Start here: Make a drawing with pencil and paper. Label everything. Add with the graphite end and remove with the gummy end. This is called a draught. A beginning.

I can definitely feel it, it's been present the whole time in this thread. :upside_down_face:

Close, but no cigar !
You might want to check your spelling

You should.

Are you saying that a draught is a beginning ?

They better... your's especially... wait... I was whut? <3

Shall I gOOgle that for you?

Apparently, our OP wasn't aware that revisions to posts are always visible - forever. So...

draught
noun

British spelling of draft

Oh draughts

Feel free to Google it, but I already know what it means in English

Long live The Revolution!
