need help here. this is for my project.
how to display 10, 30, and 50 using 555 timer and 7490 binary/decade counter??
my task is to design a shooting target system. currently i have already display 10, 30, and 50 by using 7447 ic. but the problem is now, how am i going to calculate the summation of all attempts. what i mean is i.e. 1st attempt, hit 10. the score will then display 10 n summation will also display 10. 2nd attempt, hit 50. the score will display 50 and summation will display 60 (10+50). 3rd attempt, hit 30. the score shows 30 and summation display is now 90 (10+50+30). how am i gonna display the sum??
i appreciate any suggestion or idea.
