The pins can be divided in two main functions as analog pins and as a digital pins. There are 16 analog input pins, those shaded in yellow labeled, from pin H 0 to pin a 15. Each pin provides a 10 bit of input resolution that is a range of 1024 different values from 0 to 5 volts. Next, there are 54 digital input and output pins. They are labeled from pin 0 to pin 13 from pin 14 to pin 21 from pin 22 all the way down to pin 53 all shaded in green are all digital input and output. Pins digital pin can perform other functions when called or configured in the Arduino software. They are as follows: starting with pulse width, modulation or analog output, the board provides 14 analog output from pin 0 to pin 13 each pins provides 8 bit of resolution. That is in range of 256 different values from 0 to 5 volts. The output can be sent using an analog right in the Arduino software. Next serial data communication, the board provides for UART serial data communication to be configured in Arduino software. Each serial uses the following: pins: pin 0 to receive data, pin 1 to transmit data. Serial 1 uses pin 19 to receive data and pin 18 to transmit data. Serial two uses pin 17 to receive data and pin 16 to transmit data, see real tree uses. Pin 15 to receive data and pin 14 to transmit data.
Take note. Serial 0 is utilized by the board for serial data communication via a USB interface. The digital pin supports i2c communication. This can be configured using the wire library of the arduino. Software can be set up in 20 as the data line and pin 21. As the clock line, digital pin supports serial peripheral interface or spi communication using the spi library of the arduino software and can be configured at 1050. The mi s o up pin 51 the mo si pin 52 the SC Cal and pin 53 SS once SPI is already configured. The board can communicate with different serial peripheral device over a short distance using one of the digital pin. The Arduino boards provides six external interrupt. Each interrupt can be configured on the following pins for external. Interrupt 0 can be configured on, pin number 2 external interrupts. 1 can be configured on pin number 3 external interrupts to unpin 21 external interrupts 3 on pin 20 external interrupts for on pin 19 and external interrupts 5 on pin 18 to enable a particular interrupt use. The Arduino command attach interrupts, open and close parentheses inside the parentheses indicate. The number of external interrupts, for example, interrupt 0, 1, 2, 3 or 5 to disable a particular interrupt use the command the touch interrupt, open and close parentheses indicate inside the parentheses. The number of the active external interrupts to disable all interrupts use the command, no interrupt open and close parentheses.
The Arduino mega 2, 5, 6, 0 r 3 provides 6 timers functionality, the Arduino board and the Arduino software library uses a default timer. The timer is zero configured by default at pin 13 and pin 4 timer 0 as an 8 bit resolution, and by default years by the timing function of the Arduino software library, such as the delay, the male is, and the micros another functionality not written here is The delay microseconds take note that care must be taken when experimenting with the timer 0 to avoid undesirable outcome. Next is timer 1 having a 16 bit resolution, utilizes pin 11 and pin 12 when configured in the Arduino software take note. The timer 1 is utilized by the tone library of the Arduino software. Each time a tone function is called somewhere in the program. Timer 1 is enabled. Next is timer to having an 8 bit resolution. Utilizes pin 9 and pin 10 when configured in the Arduino software. Take note also, the timer 2 is utilizes by the servo library of the Arduino software. So each time the servo library is active for each serve, both function is active. Timer 2 is enabled. Next is timer 3. Having a 16 bit resolution, utilizes pin 2 entry and pin five when configured in the Arduino software, unlike timer zero one and two timer three is free from any default functions in the Arduino software library. Next is timer for also 16 bit resolution utilizes pin 6 7 amp 8, like the timer tree.
Timer 4 is also free from default function in the Arduino software library. Next is the timer 5 timer 5 has a 16 bit resolution, which utilizes pin 44 45 and pin 46 timer 5 like timer for or timer 3 is free from any default functions in the arduino software library. Now we are ready to identify the power pin. Connections of the word whole shaded in red power pin connections. As you can see around the world, you have access to power, source or grams. You have two grounds here. We are following the arrow cursor. You have another 5 volts of output here and another ground connections. Here so you have power, pin headers, so we are going to zoom in so in this pulp, our headers, you have voltage input. You have two grounds. You have five volt source and 3.3 volt source. You can use voltage input connectors to power the board.
