Okay, NoObisch Q,I wonder how I would know how many Ohm a resistor should be, when I am designing a circuit on my own.Like the KnightRider example, they use 220 Ohm, why (and why use a resistor here anyway??)I am also using Google offcours, but here I have a feeling I can ask stuff I don't get.(I have a medical background, doing electronics as a hobby).Thnx for the time and Greetz from the Netherlands!!
sorry:I = V/R = 5V/1kOhm = 5mA // how do you get 1mA?
