I am getting into electronics so I can build circuits for various model railroad projects. My background is mechanical engineering, so please bear with me if my questions seem simplistic.
I bought a breadboard and an assortment of 3mm and 5mm LEDs so I can experiment with some battery powered circuits. An LED needs a resistor to limit the amount of current flowing through it. Assuming I will be stringing about 4 LEDs in series, what values of 1/4 watt metal foil resistors should I buy in an assortment package? My thoughts are an assortment of 200 to 976 Ohms with a 1% tolerance.
