Hi, This is my first post.
I left Uni 20 years ago (instrumentation and robotics) so the electronic part of my brain is a bit rusty.
Can anyone help with 2 really simple circuits (so simple that I can't do them!)
For an output that reaches 1 v I would like to power up an LED and leave it on until it drops below 1v again.
Secondly for an output that varies from 0 v to 0.7 v then up to 5.0v
I would like an LED to light when it gets to above 0.6v and then shut off above ,say, 1.0v and then a second LED to light when it gets to above 4.8 volts up to 5.5 volts
Both LED's need to turn off if the voltage drops below those numbers.
Any help would be greatly appreciated
