To achieve this with an ESP32-CAM, you'll need to program it to capture a photo when the button is pressed and then send that photo to Telegram. Here's a general outline of how you can do it: Set up your ESP32-CAM: Make sure you have the necessary libraries installed for your ESP32-CAM, and ensure it can connect to your Wi-Fi network. Connect a button: Wire a button to one of the GPIO pins on your ESP32-CAM. When the button is pressed, it will change the state of the GPIO pin, which your code will detect. Capture a photo: Write code to capture a photo using the ESP32-CAM's camera module. This could involve using libraries like esp32-cam-telegram or similar. Telegram Bot: Set up a Telegram Bot and get the necessary API token. Send the photo to Telegram: Write code to send the captured photo to Telegram using the Telegram API. You'll need to use the API to upload the photo and send it as a message. Here's a basic example of what the code might look like: #include <WiFi.h> #include "esp_camera.h" #include <UniversalTelegramBot.h> #define BUTTON_PIN 13 // Change to the GPIO pin connected to your button #define CAMERA_MODEL_AI_THINKER // Use appropriate model for your ESP32-CAM const char* ssid = "YOUR_SSID"; const char* password = "YOUR_PASSWORD"; const char* botToken = "YOUR_BOT_TOKEN"; WiFiClientSecure client; UniversalTelegramBot bot(botToken, client); void setup() { pinMode(BUTTON_PIN, INPUT); Serial.begin(115200); camera_init(); connectToWiFi(); } void loop() { if (digitalRead(BUTTON_PIN) == HIGH) { captureAndSendPhoto(); delay(1000); // debounce delay } } void camera_init() { camera_config_t config; config.ledc_channel = LEDC_CHANNEL_0; // initialize the camera module esp_err_t err = esp_camera_init(&config); if (err != ESP_OK) { Serial.printf("Camera init failed with error 0x%x", err); return; } } void connectToWiFi() { Serial.println("Connecting to Wi-Fi..."); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { delay(1000); Serial.println("Connecting to WiFi..."); } Serial.println("Connected to WiFi"); } void captureAndSendPhoto() { camera_fb_t * fb = NULL; // Take a photo fb = esp_camera_fb_get(); if (!fb) { Serial.println("Camera capture failed"); return; } // Send the photo to Telegram String photoName = "/photo.jpg"; if (bot.sendPhoto(CHAT_ID, fb, photoName, "Photo Caption") == false) { Serial.println("Failed to send photo"); } esp_camera_fb_return(fb); } Remember to replace placeholders like YOUR_SSID, YOUR_PASSWORD, and YOUR_BOT_TOKEN with your actual values. Also, ensure you have the necessary libraries installed and configured properly. This is just a basic example, and you may need to adapt it to fit your specific requirements and hardware setup.
