hello, I have a question about Blynk and the camera.
I’ve made a project, took pictures using esp32 cam, the picture will appear on blynk.
with this tutorial, but I have a little change, where I add the button widget on blynk. which is useful for triggering taking pictures
this is the program
#include "esp_camera.h"
#include <WiFi.h>
#include <WiFiClient.h>
#include <BlynkSimpleEsp32.h>
//
// WARNING !!! Make sure that you have either selected ESP32 Wrover Module,
// or another board which has PSRAM enabled
//
// Select camera model
// # define CAMERA_MODEL_WROVER_KIT
// #define CAMERA_MODEL_ESP_EYE
// #define CAMERA_MODEL_M5STACK_PSRAM
// #define CAMERA_MODEL_M5STACK_WIDE
#define CAMERA_MODEL_AI_THINKER
#include "camera_pins.h"
// #define LED 21
// #define BUTTON 15
const char * ssid = "xxx";
const char * password = "xxx";
char auth [] = "xxxxx";
String my_Local_IP;
void startCameraServer ();

{
if (param.asInt ())
{
capture ();
}
}
void capture ()
{
uint32_t number = random (40000000);
Blynk.notify ("Someone is at the door ..");
Serial.println ("http: //" + my_Local_IP + "/ capture? _Cb =" + (String) number);
Blynk.setProperty (V1, "urls", "http: //" + my_Local_IP + "/ capture? _Cb =" + (String) number);
delay (1000);
}
void setup () {
Serial.begin (115200);
Serial.setDebugOutput (true);
Serial.println ();
camera_config_t config;
config.ledc_channel = LEDC_CHANNEL_0;

} else {
config.frame_size = FRAMESIZE_SVGA;
config.jpeg_quality = 12;
config.fb_count = 1;
}
#if defined (CAMERA_MODEL_ESP_EYE)
pinMode (13, INPUT_PULLUP);
pinMode (14, INPUT_PULLUP);
#endif
// camera init
esp_err_t err = esp_camera_init (& config);
if (err! = ESP_OK) {
Serial.printf ("Camera init failed with error 0x% x", err);
return;
}
sensor_t * s = esp_camera_sensor_get ();
// initial sensors are flipped vertically and colors are a bit saturated
if (s-> id.PID == OV3660_PID) {
s-> set_vflip (s, 1); // flip it back
s-> set_brightness (s, 1); // up the blightness just a bit
s-> set_saturation (s, -2); // lower the saturation
}
// drop down frame size for higher initial frame rates
s-> set_framesize (s, FRAMESIZE_QVGA);
#if defined (CAMERA_MODEL_M5STACK_WIDE)
s-> set_vflip (s, 1);
s-> set_hmirror (s, 1);
#endif
WiFi.begin (ssid, password);
while (WiFi.status ()! = WL_CONNECTED) {
delay (500);
Serial.print (".");
}
Serial.println ("");
Serial.println ("WiFi connected");
startCameraServer ();
Serial.print ("Camera Ready! Use 'http: //");
Serial.print (WiFi.localIP ());
my_Local_IP = WiFi.localIP (). toString ();
Serial.println ("'to connect");
Blynk.begin (auth, ssid, password);
}
void loop () {
// put your main code here, to run repeatedly:
Blynk.run ();
}
BUT, the picture is not satisfactory.
I want to replace the board or camera. I want to use a TTC vc0706 camera and a nodemcu.
Can it be applied using blynk?
Thank You
