Arduino Stopwatch Recorder

A sophisticated stopwatch system powered by Arduino. This isn't just any timer – it's a meticulously crafted instrument that combines the power of two Arduino Nano boards. The Master Arduino leads the charge in accurate time measurement, showcasing the elapsed time on a vivid LED display. But there's a twist – each time reset doesn't just stop the clock; it triggers an intricate process where the elapsed time is seamlessly transmitted via I2C to the Slave Arduino. This secondary unit plays a crucial role, diligently logging each time record along with the exact date and hour, thanks to the integration of the RTC DS1307 module. All these details are neatly packed into a text file on an SD card, effortlessly readable and perfectly organized for any analytical needs. Whether you're a hobbyist, a student, or a professional seeking a reliable timing solution, our Arduino-powered stopwatch is the ideal tool, merging the realms of accurate timekeeping and efficient data recording. Discover the blend of technology and precision with our project – where every second is accounted for, and no moment goes unrecorded.
