#185575 - Switch interfacing
Responding to: ???'s previous message
plz can any one tell me how i post schematic of my project after seeing my schematic may some have any idea for my project.

i smmries my project here. because no any one understand whats my problem.

componenet used

1-- microcontroller(1)
2-- 4094 shift register(5)
3-- seven segment display(5)
4-- push button(4)

i connected 4094 in serial and take three input(data,clock,strob) on first
4094 and each 4094 is connected to seven segment display.

problem is that i want to do that when i press first push button it select first seven segment after it when i press second switch increament in digites in first seven segment after it when i press third switch it decrease in digites in first seven segment after it when i press 4 switch it showas all digites .
same thing in other even segment also.

all over menan in one time change in only one seven segment display/


if any one have any idea plz tell me.
