@@ -13,13 +13,13 @@ The following table summarizes GPIOs and pins reserved for operations purposes.
The GPIO numbers correspond to those on the ESP32-C3 WROOM microcontroller. The Pin number corresponds to the pin on the Breadboard and Power adapter development board.
x- and y- axis
~~~~~~~~~~~~~~
Reading x- and y- axis
~~~~~~~~~~~~~~~~~~~~~~
The **GPIO0** and **GPIO1** assigned to measuring the voltage of x- and y- axis of the Joystick. Lastly, there is a group of GPIO pairs responsible for PWM for DC motors.
Direction and Speed
~~~~~~~~~~~~~~~~~~~
Controlling Direction and Speed
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The pairs of DC motors on the left side are wired to the dedicated PWM channels. This means that *ESP32-C3 Breadboard DevBoard* can control rotation speed and direction of DC motors in pairs only (i.e. left and right side).
Consequently, only four PWM channels are sufficient for controlling the direction of the RC car.
