Pan Tilt ESP32 Cam Web Streaming

Overview

In this project, we’ll attach the ESP32-CAM to a pan and tilt stand with two SG90 servo motors. With a pan and tilt camera stand, you can move the camera up, down, to the left, and to the right—this is great for surveillance. The ESP32-CAM hosts a web server that shows video streaming and buttons to control the servo motors to move the camera.

Parts Required

For this project, we’ll use the following parts:

• ESP32 CAM (AI Thinker)
• FTDI
• Pan and tilt stand
• Jumper wires
• Pan tilt module
• 2 * Servos SG90

Steps

1) Pan and Tilt Stand and Motors Assembly

2) Connecting Servo Motors to ESP32 and Power Supply

3) ESP32 CAM Case Assembly

• STL files:
  • Top Model on Sketchfab
  • Bottom Model on Sketchfab
  • Mount Model on Sketchfab

4) ESP32 CAM Programming

• FTDI <=> ESP32 CAM Wiring
  

• Software and Code Setup:

  1. Install Arduino IDE
  2. Download the code
  3. Download libraries & ESP32 board:
     • Open pan_tilt_esp32_cam sketch in Arduino IDE
     • Go to Preferences in the File menu
       
     • Paste this URL in Additional boards manager URLs: https://dl.espressif.com/dl/package_esp32_index.json
       
     • Go to Boards Manager, search for esp32, and install version 1.0.6
       
     • Go to Library Manager, search for esp32Servo, and install version 0.11.0
       
     • Setup the ESP32 CAM board
       
     • Upload the code to the connected ESP32 board using the FTDI module
       

5) Web Application

• After uploading the code, remove the jumper wire
  
• Press the reset button
  
• Open the IP address in a browser connected to the same Wi-Fi network
