Hello there, As an experienced Arduino developer, I am excited to propose the creation of custom firmware for your project. My goal is to design a robust Arduino Uno code that seamlessly integrates a fingerprint reader (via UART), an LCD display, and 14 relays to fulfill your project requirements. The system will accurately identify individuals based on their fingerprints, display their names on the LCD, and activate the corresponding relay to control designated robotic devices. Moreover, any unrecognized fingerprints will prompt a relevant message on the LCD without triggering any relay activations.
I have a proven track record in developing similar access control systems. For instance, I successfully implemented an access control system in my office by combining an Arduino, a fingerprint sensor, a relay for door control, and an Ethernet module for data transmission. This experience has equipped me with a deep understanding of pin utilization and efficient code design. Rest assured, I will efficiently optimize the available pins on the Arduino to ensure the correct functioning of your system within the specified timeline. Upon completion, I will deliver a fully commented Arduino code, a comprehensive connection diagram, thorough test results, and detailed documentation.
I look forward to the opportunity to collaborate on this exciting project and deliver exceptional results.
