The joystick used in the bitByteRider RC car remote unit outputs analog voltages ranging from 0V to 3.3V on both the x- and y-axes,
depending on the position of the joystick. These voltage levels are read by the ESP32-C3&rsquo;s ADC (Analog-to-Digital Converter) inputs.

When the joystick is in its neutral (centered) position, the ADC inputs on the ESP32-C3 receive approximately 1.65V on both axes.
When the joystick is in its neutral (centred) position, the ADC inputs on the ESP32-C3 receive approximately 1.65V on both axes.
This midpoint voltage is interpreted and interpolated into a PWM (Pulse Width Modulation) value of 0, indicating no movement or
motor activity.

What is encapsulation?
</p>
<p>
Encapsulation refers to the process of organizing and packaging data into a structured format before it is transmitted between
devices. This is a fundamental concept in networking and communication protocols, including those used in IoT systems.
