Everyone has a passion in basketball. Basketball enthusiast never missed a single game played by their favorite team, and there were times that they wanted to speed up time or to add more time, depending if their bet-team is loosing or winning. Nevertheless, time is an important not just in basketball, but for every sports and in every day of our life. Sad to say, I cannot teach you how to speed up time but I will teach you how to make the digital clock in the basketball. 

- as far as I am concerned, 1 quarter in basketball is about 10 or 15 minutes. Since there are many possibilities of time per quarter we want to make a digital clock which can be set from 10 minutes to 15 minutes. Though we can make a basketball clock which starts at 99:99 and set it manually, I will teach you to make a basketball clock which will start at 15:59 and you can set it from there.

- I already made a tutorial regarding extracting the second and the minute hand of the basketball game clock. You can read the instruction from this post of mine and come back here after you made it.

The minute-hand circuit of the basketball game clock

· Simulate the designed circuit

- Since we are already done making the circuit diagram of our game clock, we can test it with our circuit simulator to see if it is running properly. Then after simulating we buy the materials needed.
