It counts number of ones upto a count of 14. Generally, designed to use as a max 14 bit ones counter. It can count more numbers with lower bits cumulatively, if the count of ones doesn't exceed 14.
How to use?
-> Notice the graphs (swipe down on map to distribute the graphs).
-> Control your input by switching the rightmost digital key.
-> Count the number of bits to input by clock's upward edge.
-> Number of ones is apparent from the purple graph's edges.
-> After inputting desire value, see the LEDs, which has place values of 8 4 2 1.
-> To re-input another number, just reset the simulation.
Explanation :
Suppose we input a digital number say, 11001110011010.
It has 2+3+2+1 = 8 ones.
So, LED's will glow as 1000.
