Internet races on micromachines!?

Question

Raspberry Pi

There is 1 r / y car, you need to do it in such a way that it would be controlled from the browser, that is, so that I or another user who registered on the racing site could control this car and there was a video broadcast from this car to the user's page
How can I do this ?
You need to do it like this:
habrahabr.ru/company/virt2real/blog/119000
There is a Raspberry pi, I would like to do this for 2-3 machines.
I found this:
habrahabr.ru/post/183112
But it’s expensive, and the machine is big, I need a micromachine
And the board is fixed on the machine, but I need the board not to be on the machine, that is, I need something that would send a signal to the remote control from cars and activated Gas-brake Left-Right
And I need something that would not change the appearance

Answer 1

On the Raspberry pi, set up a service that will listen to requests from your site. It can be either web or whatever your heart desires. When calling a service, pull the corresponding leg of the gpio. Connect the remote control from the typewriter to the leg.
