Remote control system that enables wireless photography and video recording using an Android phone and a Wi-Fi network. The proposed system consists of an Android application, a microcontroller, a Wi-Fi module, and a camera. The Android application allows the user to remotely control the camera's focus, zoom, and shutter using their phone's touchscreen. The microcontroller esp32 and Wi-Fi module are used to establish a wireless connection between the camera and the Android phone to capture the images and can be send to our mobile phone. The ESP32- CAM is programmed to send signals to the servo motors, which rotate the camera in the desired direction. The ESP32-CAM board is connected to a power supply and to the servo motors via jumper wires and a breadboard. The board is programmed using Arduino IDE to control the servo motors. The code sets the initial positions of the servo motors, and creates a control interface for the pan-tilt movements. The control interface is accessed through mobile device connected to the same network as the ESP32-CAM. The ESP32-CAM continuously receives signals from the control interface and sends corresponding signals to the servo motors, allowing the user to move the camera in any direction. The system also supports video recording and live preview of the camera's view finder on the Android phone's screen. The proposed remote-control system provides a cost-effective and user-friendly solution for photographers and videographers who want to control their cameras wirelessly and remotely.The basic functioning of a ghee-making machine involves heating butter in a vessel or tank, separating the milk solids from the liquid fat (clarification), and filtering the pure ghee through a fine mesh or cloth. Some machines also come with features such as automatic stirring, temperature control, and in-built filtration systems. While a ghee-making machine can save time and effort compared to traditional methods of making ghee, it is important to note that the quality of the final product depends on the quality of the butter used and the skill of the operator. Sensors and the microcontroller-based automated intelligent ghee-making unit will greatly add technology to the individual kitchen. The proposed unit will increase the quality of ghee prepared and ensure uniform ghee. It is also cost-effective so that units can be greatly accepted by individual kitchens, especially in India. The proposed Electric vehicle control system is implemented on a prototype tricycle chassis. Overall, the paper proposes a cost- effective motor drive control system for electric vehicles, with closed-loop PWM control and an electronic differential control loop. It offers efficiency, reliability, and a smooth driving experience, making it an ideal solution for sustainable transportation and a significant contribution to the field.
