I first used the "Tiny RTC" DS1307 real-time clock. This is good platform for prototyping Arduino projects, along with many other similar platforms. Package Dimensions: 9.7 x 8.3 x 5.I prototyped the design with a SparkFun Inventor's Kit which includes an Arduino Uno board, breadboard, jumper wires, etc. Learn how to use these sand timers effectively for increased productivity.įollowing the simple work-rest pattern in our bonus productivity guide, you can squeeze in more work, eliminate distractions, and achieve your objectives.
