Its just one hour stop watch.If the work area is larger ,I may be able to make a full 24 hour clock...also I made this to understand the usage of AND,OR,NOT gates .......and I learned most of it. AND is basically a gate which process two types of signal (0 and 1)and give the desired output( we can calculate this my multiplying the two binary signals....
for eg:0*0=0 [1 is +ve and 0 is -ve
1*0=0 signal.you all know
0*1=0 that by now!]
1*1=1
So when only two input is positive we get the output as positive,and if any input pin is negative the output will also be negative......
NAND gate is just the opposite of AND gate ......I hope this helps to beginners.........
