<h1>OVERVIEW<a class="headerlink" href="#overview" title="Link to this heading">¶</a></h1>
|
||
<p>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.</p>
|
||
<p>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.</p>

<h2>ABSTRACT<a class="headerlink" href="#abstract" title="Link to this heading">¶</a></h2>
|
||
<p>At the core of this project lies a shared data structure that encapsulates the control parameters for the DC motors, specifically their rotation speeds,
|
||
which are modulated using Pulse Width Modulation (PWM). This structure ensures consistent interpretation of control signals between the transmitter
|
||
and receiver.</p>
|
||
<p>The system employs ESP-NOW, a low-latency, connectionless communication protocol developed by Espressif, to facilitate wireless data exchange between
|
||
the transmitter and receiver modules. Both devices are based on ESP32 microcontrollers and maintain a synchronized understanding of the data structure
|
||
to ensure seamless communication.</p>
|
||
<p>On the transmitter side, joystick input is continuously read and translated into control values. These values are then encapsulated into the
|
||
predefined data structure and transmitted via ESP-NOW to the receiver.</p>
|
||
<p>The receiver module listens for incoming ESP-NOW packets, de-encapsulates the joystick data, and converts the received values into PWM signals.
|
||
These signals are then used to control the speed and direction of the DC motors, enabling real-time remote operation of the vehicle.</p>
