WiFi RC Car controller via a RESTful service that runs on a ESP8266 directly on the car.
This controller is meant to be used in a cheap toy RC car, overclocked and pimped. The modifications of the RC car come down to this:
- Disassemble the toy car
- Remove the original circuit board and wiring, if the car came with a rechargeable battery, keep it.
- Install the software into the ESP8266
- Buy a cheap dual H-Bridge from eBay or BYO, and install it to each motor, connect it to the ESP8266.
- Boot up and enjoy
Default pinout:
| Pin | Action |
|---|---|
| 2 | steering right |
| 3 | steering left |
| 5 | accelerate forward |
| 6 | accelerate backward |
The simplest way to use the car is to connect to its AP and use the web page. Another way is to consume the API from your custom software.
Parameters are sent to the API methods in the request body, as a json containing the required parameters
Moves the car in the indicated direction with the indicated intensity in the acceleration and steering.
| Name | Minimum | Maximum |
|---|---|---|
| acceleration | -128 | 127 |
| steering | -128 | 127 |
A request containing these parameters would slowly accelerate while steering left in a circle.

"acceleration":30,
"steering": -200
}- Write better docs
- Create a more flexible web server
- Migrate to a proper Json-POST based RESTful service
- Support better control for both axis
- Document the http server and give it away
- Add touch controls to the website for use in smarthpones
- Get more resilient (aka, test with a monkey)
- Support some network discovery
- configuration via a smartphone, and maybe a mic
- add some sort of auth
- save AP list in json file
