COCOFUEL: A Microcontroller-Based Biodiesel Production Machine

Abstract

In the global landscape, the coconut stands out, with over 61 million tons harvested annually, yielding approximately 75 coconuts per tree annually. Recognizing its multifaceted benefits, including its suitability as a biofuel, various countries have endeavored to develop biodiesel production machines, each employing distinct methodologies and chemical compositions. Central to these efforts has been the drive to optimize production efficiency while minimizing costs, encompassing chemical inputs, procedural complexity, and energy consumption. This project undertook the design and implementation of a microcontroller-based machine tailored exclusively for biodiesel production via the transesterification method, utilizing coconut oil, methanol, and a catalyst. Adopting the Rapid Application Development framework, the project unfolded through iterative cycles, encompassing analysis, design, prototyping, testing, and refinement. The machine’s core functionalities were orchestrated by the Arduino Mega microcontroller, orchestrating the operation of washer motors, solenoid valves, and the heating rod, complemented by a relay, Bluetooth module, and voltage regulator. Thorough testing and evaluation underscored the machine’s reliability and efficacy in producing biodiesel from coconut oil, marking a significant stride toward renewable en ergy advancement. This accomplishment not only heralds progress in green energy solutions but also offers a compelling response to the environmental imperatives associated with conventional diesel fuels. The potential for reduced carbon emissions and the promotion of environmental sustainability amplifies the significance of this development, charting a course toward a greener future through the synergy of natural resources and cutting -edge technology.
