"how do u display digits/ patterns on the 7-segment?"?

Answers:

depending if it is positive sink or negative sink, you apply a common, again either + or -, and each segment is connected to one of the pins extruding from the bottom. by applying the opposite polarity to the desired pin. I suggest using a resistor inline with each pin to prevent burning up the led. about a 330 ohm will do. Dont apply more than 5 volts to the led display or you will blow the led.

Other answers:



Use the correct voltage and a current limiting resistor.
