forgive me for what I said about ChatGPT.
it is cool as it gets. I will the code a try tonight.

generate esp-32 cam code that has a web interface that shows a live stream and can control a stepper motor with 2 buttons. one button to rotate clockwise and one button to rotate counterclockwise while the button is held down

Code:
Sure! Here's an example code that uses ESP32-CAM with a web interface to display a live stream and control a stepper motor with two buttons. One button is used to rotate the motor clockwise, and the other button is used to rotate it counterclockwise while the button is held down. Make sure you have the necessary libraries installed before compiling and uploading the code to your ESP32-CAM board.
Code:
#include <WiFi.h>
#include <WiFiClient.h>
#include <WebServer.h>
#include <ESPStepperMotorCtrl.h>
#include <esp_camera.h>
// Replace with your network credentials
const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";
// Create an instance of the web server
WebServer server(80);
// Set GPIO pins for stepper motor control
const int stepPin = 14; // Step pin
const int dirPin = 27; // Direction pin
const int stepsPerRev = 200; // Number of steps per revolution
// Create an instance of the stepper motor controller
ESPStepperMotorCtrl stepper(stepsPerRev, stepPin, dirPin);
// HTML web page
const char* htmlPage = "<html>\
