The ESP32 Cam is a small camera that can be used to take pictures and videos. The servo is used to pan and tilt the camera. This can be used to create a security camera, a robotic eye, or anything else you can think of. We will also show you how to use a web interface to control the camera. THANKS, NEXTPCB I would like to thank the Nextpcb for supporting me on every project. If you have a PCB project, please visit the Nextpcb website to get exciting discounts and coupons as follows: Step 1: Required MaterialStep 2: Assemble Tilt Kit With Servos MotorThis fully-assembled pan-tilt kit is an excellent way to give your project the greatest range of motion with two servos. The pan-tilt can rotate around 180° from side to side and can tilt up and downwards near 150°. It also comes fully assembled with two Micro Servos (SG-90 type) included and a 38mm x 36mm space to mount a camera. You can use any microcontroller. They are suitable for beginners who want to make things move and the pan-tilt is an effortless way to give whatever you are making both left, right, and up-down motions. Servo motors have three wires with different colors: Step 3: ESP32 Cam ModuleThe ESP32-CAM is a development board with a built-in camera. It is based on the ESP32 chip and can be used to take high-quality still images and video. The ESP32-CAM can be interfaced with a variety of sensors and peripherals to create a powerful camera system. We ESP32-CAM development board to control two servos that act as a pan-tilt mechanism for a camera. We’ll first write the code to control the servos using the Arduino IDE, For this project, we’ll be using the SG90 servos, which have a minimum pulse width of 500 microseconds and a maximum pulse width of 2500 microseconds, we’ll be using a range of 0 degrees to 180 degrees for each servo. The servo motor is a type of electric motor that can be used to control the position of an object. Servo motors are often used in robotics applications to control the movement of a robotic arm or leg. Servo motors are also used in radio-controlled airplanes and cars to control the movement of the control surfaces. Step 4: Wiring DiagramThe wiring diagram is very clear. You have to connect the servo motor pins with ESP32 pins as per the schematic diagram. The schematic diagram is shown above. Connect all parts using the schematic. Use a piece of double-sided tape to attach the ESP32-CAM to the Pan/Tilt. Step 5: Setting Up ESP32 Development BoardYou can program the camera module using the Arduino IDE. After you have installed the development environment, you can open it to prepare you for using the camera module. 1. Start Arduino IDE and open the Preferences window. 2. Enter https://dl.espressif.com/dl/package_esp32_index. into the File>Preferences>Additional Boards Manager URLs field of the Arduino IDE. You can add multiple URLs, separating them with commas. 3. Close this window with the OK Button. Open Boards Manager from Tools > Board menu and select the correct ESP32 Cam board.

Now you will be able to see the live video on the Smartphone. I am super happy with the final outcome of this little gadget. You may gift this little gadget to someone on any occasion Be the First to Share Page 3The whole idea came to me during the early covid-19 days, when my whole family (2 parents, 3 kids) was forced to remain at home, and both parents desperately attempting to get some work done from home. After being interrupted time after time during voice and video calls I thought to myself how handy it would have been if I had an electrical sign that can display my current status, whether I'm in a call, my video cam is active and so on (if you ever tried to work from your bedroom and had to signal your partner that its probably not a good time for changing shirt while standing behind you, you know what I'm talking about) Well, I couldn't find any, neither I had any real Arduino experience back then, but I do have quite some C and embedded programming experience plus some knowledge in electronics. So by the time we were having the second Covid lockdown, I had the parts available plus the extra time as there wasn't much else to do. How does it workThe Arduino part is pretty simple, I used an Arduino nano cheap clone wired to a LED matrix. The Arduino software is capable of displaying two elements, representing the microphone and the speakers and adding an animation overlay to signal when they are in use. It is controlled from a host PC by a USB cable, using a made-up text based protocol that allow the host PC to detect the connection status and control the display status. The host part is a simple WinForms application (written in c#) that polls the host PC microphone and speakers status and update the LED display accordingly. Required hardware and pricing
