1.Introduction:
  It is a 6Bit Digital Electronic Clock DIY Kit. It integrates six functions: time, alarm clock, calibration, countdown, stopwatch and counter. It is easy to operate, very suitable for home or office environment.

  Great School Science Project: The DIY Clock Kits are used to installed to a 6-Digit Digital Electronic Clock. It is widely used in schools to help students learn basic mechanical and electronic skills. It's a great Science Fair project. Highly recommended to practice soldering skills enjoyably for you.

  Wide Time Functions: Wide functions with clock, time set, alarm set, countdown timer, stopwatch, counter, hourly chime, precise time display, and 24 hours format. Accurate Travel Time--the error range ±1 sec every 24 hours.

  Easy Assembly: In addition to teaching basic mechanical and electronic principles, the clock kit is easy to build and is so simple. The connection that was clearly mapped and labeled on the board makes it easy to assemble. It's often used to teach basic soldering skills. It's a great first kit for any STEM student. No programming is required.
