Hi Mike ML, The simplicity of your first circuit is exactly what I'm looking for (The one that turns the Led on when V(i) is greater than 1v.
What changes would I need to make to this to turn another red led on when V(i) is greater than 4.7 v.
Also do you agree with EinarA on the...
Hi Alec.
Basically I have a sensor circuit that will deliver an output up to 5.5 v.
This output will be the input for my LED display circuit which has a 5v supply but for ease of design you could assume a 5v max for both circuits.
There are only 2 leds on the second circuit. 1 will turn on...
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...
