Limit Switches with LED's

[manofgresley]

Hi Jonathan
Thanks for all your help, seems like i was asking for quiet a lot when i said simple. Forgive me but you lost me at OP AMP / Comparator, and can you explain what a gui is from a previous post?
This is my latest interpration, do you think it will work, i realise that the only LED to illuminate will be the one on the activated switch.

Regards and Thank You

OP AMP / Comparator gui

An Operational Amplifier is wonderful thing. It has 2 inputs labled + and -. If the Voltage on plus is higher than the Voltage on minus the output pin goes high, vice versa and it goes low. With a bit of resistor jiggery pokery you can multiply or divide a voltage by anything you like.

If they make an Op amp and it turns out to be too clunky they mod the circuit to lose the drive high on the output and call it a comparator. You connect your input to one pin, a reference Voltage to the other and the output tells you which is the higher.

GUI usually stands for Graphical User Interface.

I can't comment on your circuit because I still don't know what is coming out of the Bob.
