How-to: Connecting a 7-segment LED to the Arduino

Jeff posted this nice how-to on wiring up a 7-Segment LED to an Arduino. His code uses the ‘map()’ function to scale the sensor data and display it’s relative value on the 7-Segment display. This is a good project to try out, after you make the infamous pin 13 blinking LED. [via arduinofun]

    shouldn’t you use a resistor for each segment instead of a common resistor? Sure its only a quick build but if its a how to then it shouldn’t cut corners like that and try to teach people bad habits.
