Join Zahraa Khalil for an in-depth discussion in this video Wiring up the 7-segment LED, part of Learning Arduino: Interfacing with Hardware.
- [Narrator] So now in this section,…we're going to go through the wiring…of the seven segment LED to the Arduino board.…Since the seven segment LED has seven LEDs…so we need the resistor when we connect…the seven segment LED to Arduino.…Again, the only difference between…having a common anode and a common cathode…is that the common pin within the seven segment LED…is connected to five volt if we're using a common anode,…and is connected to ground if we're using a common cathode.…
We're going to use a common anode for our example,…so let's see how we do the wiring.…So for the wiring part we are going to follow…the table that's shown in the screen.…So for example, for the seven segment LED pin…a, which is pin seven, is going to be connected…to pin two, to the digital IO in the Arduino board.…Pin b, which is pin six in the seven segment LED,…is going to be connected to pin three,…and so on for the rest of them.…So let's go ahead and do the wiring for the seven segment.…
So I've included a picture of the wiring diagram…
