Hi all
I am trying to build a board to go alongside my 13.8V (maplins, XM20W) bench power supply. I want to be able to switch between a 5V and 9V regulated power supply.
I also want to include a 7 segment display showing 5 or 9, depending on the current voltage selected.
Can anyone please confirm if they believe this will work/fail?
Will segment B be as bright as all the other lit segments when I am displaying a 9? I haven't decided on the resistors to be used yet, but this should only affect the brightness between 5 and 9 and not the seperate segments, right?
Any opinions/ideas/criticisms appreciated!
Thanks!!!
