Iot Based RC Car Lap Timer

Abstract

This project focuses on designing an innovative lap timing system tailored for RC car racing, aimed at enhancing the accuracy and reliability of lap time measurements crucial for determining race rankings. Existing lap timers for RC cars often rely on manual triggering, which impacts accuracy due to the manual start-stop process. To address this, we developed a system based on specific requirements identified through market research, utilizing experimental, observational, and testing methodologies for comprehensive data analysis. Several experiments were conducted using different sensors to optimize performance, employing both qualitative and quantitative analyses. The selected concept demonstrated promising theoretical accuracy. The hardware design incorporated enhancements aligned with the project objectives, while the software architecture ensured seamless integration. Our study results show that the developed lap timer significantly improves the accuracy of lap time measurements for RC car racing. Key focus areas included the sensor's detection range, the sensor's distance, and the RC car's speed at detecting the sensor. Verification was carried out using a device that met minimal acceptance criteria, as it was not possible to achieve the required accuracy in the verification device. Nevertheless, the designed system closely met its intended specifications. The findings are not only relevant to the RC car enthusiast community but also provide insights for the broader field of recreational electronics. This lap timing system offers a valuable enhancement to the RC car racing experience, contributing to the ongoing development of technology within the hobbyist community.
