Was it Hashtag One Two who linked an IC that drove 4 7 segment displays, that was a month or so ago?That is very easy with an MCU or dedicated driver chips, are there any constraints on what you 'can' use or what you 'must' use.
There are literally hundreds of ways to do this.
Are you perhaps supposed to be doing research as oppose to asking for a solution?
What is your input, Binary value, BCD value, analogue value ... the list go's on
You will have to define the problem to find an answer, however you get there.
yes we use 4 bits, and use LED as the indicator.If you have 4 bits, then 2^4=16 states, state 1 is 0000 which is decimal zero, state 16 is 1111 which is 2^3+2^2+2^1+2^0=8+4+2+1=15.
How many bits to do you need to get to 99?
http://www.electronics-tutorials.ws/counter/bcd-counter-circuit.html take that and don't let it count to 99, you will have 0001 for the tens, 0101 for the single units. That is 1 and 5 in decimal, which will be shown as 15. When your next count of 16 comes up, the 0001 of the tens will be the same, but the single units will change from 0101 (decimal 5)to 0110 (decimal 6). Take bits from each counter that determine that you have 16 and run them to a logic gate that will generate desired output needed to feed the reset signal on the counters.yes we use 4 bits, and use LED as the indicator.
before i get that test from my teacher, we already learn with 2 counter 7473 (4bit),1 sevent segment, one 7447 ic, and u know that sevent segment will display 0-9 decimal and 10-15 showing different number(ex 10 like alphabet c).
Our new job is make the number 10-15 to show as decimal using 2 sevent segment. what components we need to make that project?
Two seven segment displays are CAPABLE of displaying the decimal digits from 00 to 99. In fact, they are capable of generating 2^14 = 16,384 distinct patterns. What determines the patterns that they WILL display is the logic driving them. Consider a digital clock that uses two 7-seg displays for the minutes -- it only displays the numbers 00 to 59. The two displays used to display the hours only displays the numbers 1 to 12 (on most clocks). Again, it's the logic driving the display that determine what they will actually display.my teacher ask me to create project using 2 sevent segment to display only 0-15 decimal. but i think if using 2 sevent segment, the display will show 0-99 decimal.
It's possible to display only 0-15?
