my project is as follows:
i have to bould a system that can eb able to count a number of objects and display using 7 segments the number counted. if a certain number of objects is reached, the circuit should switch off using a relay and turn on again after 10 seconds to count again.
my ideas:
-i will use a phototransistor to detect the object
-use a counter to count the object
-use 7 segment to display the number of objects
-use a time switch (relay) to switch off the system
i need some suggestions and tips in order to complete the project
what i need exactly is : the type of circuit elemets and maybe circuit diagrams for the porject
