INTRODUCTION
|
|
============
|
|
|
|
At the heart of this project is a customizable remote-controlled car that responds to real-time control inputs — capable of handling speed adjustments,
|
|
directional changes, and even extended features like lights or sensors. The foundational setup uses ESP-NOW for transmitter and receiver devices,
|
|
allowing you to wirelessly guide the car's behavior. While the design and physical appearance of the RC car can vary wildly depending on your
|
|
creativity and available hardware, the control system remains elegantly efficient. To facilitate wireless communication between devices, the system employs
|
|
ESP-NOW, a lightweight and connection-free protocol ideal for fast, low-latency data transmission between ESP32 microcontrollers. Though ESP-NOW is used under
|
|
the hood, the spotlight remains on the RC car itself: how it moves, adapts, and evolves with your ideas.
|
|
|
|
An ESP-NOW-based remote-controller sends control data wirelessly using the ESP-NOW protocol to the remote-controlled car. ESP-NOW enables fast and
|
|
efficient communication between ESP32 devices without the need for Wi-Fi router, network nor pairing. The provided tutorial demonstrates a functional
|
|
setup where a transmitter sends data to a receiver to define the car's speed and direction — forming the core communication loop. While the baseline
|
|
implementation focuses on movement, additional features like lights, sensors, or telemetry can easily be integrated by expanding the source code. This
|
|
modular design gives users the freedom to customize both the appearance and behavior of their RC car, resulting in endless creative possibilities.

ABSTRACT
|
|
--------
|
|
|
|
- In the heart of this project, is data struct that contains values defining DC motors rotation speeds using PWM.
|
|
- the data struct is consistent between transmitter and receiver
|
|
- both, transmitter and receiver communicate using ESP-NOW protocol
|
|
- transmitter encapsulates values if joystic position before sending them to the receiver devices
|
|
- receiver device de-encapsulates the joystic position vallues and converts them to PWM values for setting the rotations and directions of DC motors |
