hello all, I'll appreciate any help that you guys can provide me with this small design. I am open to any suggestions, i want to make a text fixture that when you input different exact voltage readings you obtain an visual LED light. For example if you were to input 5 volts exact with a little tolerance a LED will light up .. that's it. I was thinking a simple LED circuit but if the voltage is 4.80 i need another LED to light up. Could i use a transistor to control the LED when only a particular voltage is fed?
