The joystick used in the bitByteRider RC car system 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’s ADC (Analog-to-Digital Converter) inputs. 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’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. This midpoint voltage is interpreted and interpolated as a PWM (Pulse Width Modulation) value of 0, indicating no movement or motor activity.
