Don't wait until the last minute to try to get help.so do you have any idea how can I solve this problem
hi 20,the problem that I can't use an ic circuit or transistors and I just have 9 volts
Try reading about comparators hereactually it is a project not homework.
and if I will just show that I have attempted without any positive results I will get zero out of 100.
and actually I have already read the problem statement 10 times. and the problem I am faceing that I have to let more than 4 leds light sequentially as a battery level detector and also I cant use any kinds of ic circuit (except the op-amp) also I cant use a transistor
thank u so much
It's not a lot of work and using opamps as comparators was a requirement of the assignment.Hey,
I see a lot of discussion about using op amps as comparators which soulds like a lot of work.
Being lazy in school is the best way to fail.As a proper, lazy engineer you want go with the simplest (and propably cheapest) solution, so why don't you just use some voltage dividers to drive the leds at different voltage levels?
