Greetings.
Im a biomedical engineering student, been following the forums for quite some time now (quite helpful), but this is my first post since i'm having some trouble figuring out this project i'm supposed to make.
Project description : (I'm implementing it on MultiSim)
Implement a circuit that allows for body temperature measuring with visual LED display.
The circuit should have a potentiometer (denominated PT-100) that will simulate the temperatures, and 3 different coloured LEDs that turn on during different temperature ranges (eg: <37ºc= green, 37ºc<yellow<40ºc,red>40ºc)
Only one LED may be turned on at any given time.
Im also allowed to use resistors, op amps, and transistors.
Now my real question is, where to start. Im considering using transistors , but i'm having a hard time figuring out the "one LED at any given time" bit.
Any insight would be greatly appreciated!
Thank you for your time.
PS: English isn't my first language, so i apologize first hand for any mistakes/bad grammar.
