Digital interfaces
- [Narrator] Let's take a look at the Arduino digital pins. Digital values or signals simply mean zero or one, so it's either on or off. So the voltage that comes out of the digital pin is zero volt when the pin is set low or five volt when the pin is set high. An example is an LED. The light is either on or off. The pins in the Arduino that we use for sending or receiving digital values are zero to 13 when using Arduino Uno, and using Arduino Maga, zero to 13 and 22 all the way to 53. Some of the digital pins can be used for other secondary purposes, now depending on the program inside the microcontroller. Example is pin zero and pin one are communication pins. Pin zero is a receive, and pin one is transmitter. If you don't have any experience with Zero communication, don't worry. I'll explain more about it later in the course. The other example that the digital pins are used for is pulse with modulation.…
