Calf rearing is a critical aspect of livestock farming, and efficient feeding plays a pivotal role in the health and growth of young animals. The significance of this project lies in addressing the challenges faced by farmers in ensuring consistent and timely feeding for their calves, thereby optimizing animal welfare and farm productivity. The calf feeding machine project encompasses several critical aspects. Firstly, it focuses on automation to streamline the feeding process, reducing manual labor for farmers. By designing a machine capable of automatically dispensing milk at regular intervals, it aims to enhance efficiency and consistency in calf rearing practices. Additionally, the project emphasizes the development of a user-friendly interface for easy operation and monitoring of the feeding process. Integrating intuitive controls and monitoring systems, it aims to empower farm workers to efficiently manage calf feeding tasks. The methodology for developing the calf feeding machine involves several key steps. Firstly, it includes the integration of a water tank equipped with a heater and sensor to monitor both the water level and temperature. A heat clock mechanism ensures that the water reaches and maintains a precise temperature crucial for calf health; the system will not operate unless this temperature threshold is met, thus remove the risk of stomach illness in the calves. Secondly, the milk tank incorporates plates driven by motors to facilitate the introduction of milk powder into a mixer. The amount of milk dispensed is regulated by the milk level sensor, which controls the flow of water entering the mixer, ensuring the correct milk concentration for the calf's nutritional requirements.the mixing component of the system includes a level sensor to monitor the milk level within the mixer. This ensures that the appropriate amount of milk is consistently available for dispensing to the calves.

The methodology encompasses adherence to engineering standards, consideration of design constraints, the design process followed, tools and technologies utilized, and project management strategies employed to ensure successful project completion. 3.2 Standards and Specifications (Codes) We managed to follow Engineering standards in Calf Feeding Machine project, going with Agile Method with weekly meetings and discussion about each of the features, Starting with the machine mechanics ending by the factory testing and modifying, we built the machine step by step, each step as a feature. 8 3.3 Constraints Economic and budget constraints: Financial constraints may have an impact on the project's size and the tools utilized in it. This is because the machine's size is determined by the volume of milk produced in a certain amount of time, which increases the need for electronic components like sensors and other parts and raises the project's overall cost. 9 Security and Accessibility Constraints: Because of the difficult conditions in Palestine. The continuous fighting in the area is one of the main obstacles since it endangers people's safety and interferes with daily life. Our ability to concentrate and work regularly on the project is hampered by the unstable environment created by the nearby war. Our progress is further hampered by the bad road conditions and the ensuing transit issues. Our inability to commute to the university daily restricts our access to necessary materials, lab equipment, and possibilities for peer and faculty collaboration. To continue moving the project forward in this scenario, alternate strategies like remote collaboration and utilizing internet resources are required. Project compilation limitations (Power): Due to differences in hardware components within the project and their varying power consumption, there was initial variation in power consumption. This led to challenges in power harvesting, especially since the components used operate across multiple power thresholds. This endeavor represents our inaugural experiment in building such a device, which involves simultaneous management of these distinct power requirements. To be clear, some components require a 220-volt source, including the water heater and mixer. Conversely, some elements operate at 5V, such as the display, while others operate at 3.3V, exemplified by the ESP. As a result, during the assembly phase, we used a versatile power supply capable of delivering diverse voltage outputs. 10 3.4 Tools and Technologies ArduinoMega Figure 3.1: Arduino Mega. In our project, we have chosen an Arduino Mega 2560, a microcontroller board from the Arduino family. It has more functionalities than the orig- inal Arduino board and makes use of the AT- mega2560 chip. It features numerous communi- cation interfaces like UART, SPI, and I2C, 54 digital I/O ports, 16 analog inputs, and may be powered by USB or an external source. It is fre- quently utilized in tasks like robotics and automa- tion that call for more I/O connections and mem- ory. We used the digital ports for writing and reading on some of the components, and we also used the serial ports to communicate with other components such as the ESP, i.e. we used 3 se- rial connections We used SCL and SDA pins to connect the LCD driver, and the rest of the parts were connected to the digital ports. 11 LCD 20X4 Figure 3.2: LCD 20x4. It is a tool for visual output and information dis- play. We used it to display writings on it so that the user can easily control the machine. It was controlled by an I2C driver. LCD Driver module with I2C interface Figure 3.3: LCD Driver module with I2C interface A specialized electronic component designed to make it easier to integrate a liquid crystal display (LCD) into electronic systems is an LCD driver module with an I2C interface. 4 wires GND, VCC, SCL, and SDA come out of it. VCC is connected with 5 volts and SCL, SDA from the driver with SCL, SDA from Arduino. 12 Flowsensor Figure 3.4: Flow sensor. The integration of a flow rate sensor, which serves a dual purpose. Firstly, it ensures the continuous monitoring of water flow, which is essential for the operation of the machine. Secondly, and most importantly, it acts as a protective measure for the water heater element. The sensor confirms the presence of water flow before the heater is activated. This precaution is vital as operating the heater without water can lead to overheating and potential damage. Therefore, the inclusion of the flow rate sensor not only enhances the reliability of the system but also significantly extends the lifespan of the water heating component by preventing dry- running conditions. 13 PT100 Figure 3.5: PT100. The integration of a PT100 temperature sensor to precisely measure the temperature of the water before it is dispensed to the calves. The PT100 sensor, known for its high accuracy and stability, ensures that the water provided is within a safe and comfortable temperature range for the calves. This is essential for promoting optimal digestion and health. 14 Power Supply Figure 3.6: Power Supply. A computer power supply converts electrical power from an outlet into usable energy for a computer’s components. It typically provides DC voltage outputs to various components. Modern power supplies also incorporate efficiency features and safety mechanisms to ensure stable and reli- able operation. IR Sensor Figure 3.7: IR Sensor. An IR (Infrared) sensor is a device that detects in- frared radiation, often used for proximity sensing, object detection, or temperature measurement. It works by emitting and receiving infrared light, and changes in the received signal indicate the presence or absence of an object or variations in temperature. IR sensors are commonly employed in applications such as automatic faucets, remote controls, and security systems. 15 RTD (Resistance Temperature Detector) transmitter Figure 3.8: RTD transmitter. In the automated calf feeding machine, a PT100 temperature sensor is interfaced with an RTD (Resistance Temperature Detector) transmitter to accurately gauge the water temperature. This setup enables the transmission of precise temperature readings in a format that the Arduino Mega can easily process. The RTD transmitter converts the resistance measurements from the PT100 sensor into a standardized output signal, ensuring reliable and accurate temperature data. This data is crucial for the control system, which relies on it to adjust the heating elements, ensuring the water is at a safe and optimal temperature before being dispensed to the calves. By using this combination of PT100 sensor and RTD transmitter, the project achieves a high level of precision in temperature management, enhancing the effectiveness and safety of the calf feeding process. 16 Fuse Figure 3.9: Fuse. Safety and equipment protection are prioritized through the strategic use of two fuses. The first fuse is placed in the circuit supplying power to the Arduino Mega, safeguarding it against potential over-current that could arise from faults in the connected input devices. This fuse acts as a critical protective barrier, ensuring that any excessive current does not reach the micro-controller, thus preventing damage and maintaining system stability. The second fuse is integrated into the power line of the output devices connected to the Arduino. This setup protects the micro-controller from any anomalies such as short circuits or overloads originating from the output side, including motors, heaters, and sensors. By isolating the Arduino from these potential issues, the second fuse plays a vital role in maintaining the overall operational integrity and longevity of the system. 17 ESP32 Figure 3.10: ESP32. The ESP32 is a versatile micro-controller devel- oped by Espressif Systems, known for its dual- core processor, built-in Wi-Fi and Bluetooth ca- pabilities, making it ideal for IoT projects. With a rich set of peripherals, low power consumption, and a cost-effective design, the ESP32 has gained popularity for a wide range of applications, from home automation to industrial IoT solutions. 18 3.5 Final Design of The Project 3.5.1 Design Process As shown in the picture, the final design of the “Calf Feeding” project appears, where all components are shown: the control panel, water valves, temperature control clock, manual operation switch, mixer, milk tank, water heater, IR sensor to calculate the height of the water inside the mixer, and the white box. In the middle of the machine is a secondary heater for the milk powder to keep the milk at the optimum temperature for the calves. Figure 3.11: Calf Feeding Final Design. To ensure the main heater operates safely and avoids damage, it should not function without water flow, as this could cause it to burn out. To address this, a start mode was created to check for water availability before the system runs. The start mode involves adding a small amount of water to confirm its presence, allowing the system to proceed with operation only under safe conditions. 19 Two conditions must be met for the system to run: 1- The temperature must be above the selected threshold (default is 35°C). 2- The infrared (IR) sensor must detect more than 18 cm, indicating an empty mixture tank. When these conditions are satisfied: - The milk motor will activate, moving the blades to push milk. - The water valve will open, allowing water to flow based on the pressure difference until the IR sensor detects 14 cm of liquid. - The mixing mechanism will operate for 20 seconds every 120 seconds to ensure proper mixing. 20 Figure 3.12: Control Unit Design. The system includes the following buttons for operation and adjustment: Start Button: Initiates the system. Stop Button: Halts the system. Auto Button: Returns the system to automatic mode from adjust mode. Adjust Button: Enters adjust mode to modify settings such as water temperature and milk volume.
