<p>At the heart of this project is ESP32-C3 IoT Link, which enables a customizable remote-controlled car to respond to real-time
control inputs, handle speed adjustments, directional changes, and even extend features like measuring system telemetry values
such as voltage, current, temperature, etc. The foundational setup uses ESP-NOW for transmitter and receiver devices,
allowing you to wirelessly control the car’s behaviour. While the design and physical appearance of the RC car can vary wildly
allowing you to control the car’s behaviour wirelessly. While the design and physical appearance of the RC car can vary wildly
depending on your creativity and available hardware, the control system remains the same. To facilitate wireless communication

between devices, the system employs IoT Link powered by ESP-NOW, which is a lightweight and connection-free protocol ideal for fast,
low-latency data transmission between ESP32 microcontrollers.</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 a Wi-Fi router, network, or 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 behaviour of their RC car, resulting in endless creative possibilities.</p>

<p>To enable real-time remote operation of the RC car, the system translates joystick x- and y- axis inputs into PWM (Pulse Width Modulation) signals that control the DC motors.
