For example, using this function like this ‘pinMode(13, OUTPUT)’ will initialize the pin number 13 as a digital output pin. To initialize any pin as an input or output, we use pinMode(pin_number, mode) function.If the switch is closed, it will sense 5 volts. For example, when the switch connected with Arduino Uno digital input is open, it will sense zero voltage level. These pins are mostly used to sense the digital voltage level presence when the switch is open or closed).
high or low or in simple words either 5 V or 0 V no in-between values.
We can use all these pins either as digital input pins or digital output pins. How can we initialize these pins for a specific feature?Īs mentioned in the last section, Arduino Uno has fourteen digital I/O pins. In this section, we will see the function of each pin. Pin Configuration Description and their use But we can use only one function of each pin at a time. Pinout diagram shows that each pin has multiple functions such as PWM, interrupts, general-purpose input-output and analog channel.
Arduino nano pinout gpio software#
We will discuss its specifications, pin configuration, dimensions, shields compatibility, software for coding, applications and projects in which this board is used. In this article, we are going to briefly discuss Arduino UNO. It is one of the most economical boards of Arduino family and is widely used because of its small number of input-output pins and reduced size as compared to Arduino mega which is the big brother of Arduino UNO. Basically is an open-source platform and is mainly based upon AVR microcontroller Atmega328.
Arduino nano pinout gpio code#
These boards are commonly used as they are inexpensive, cross-platform (IDE software which is used to make a code for these development boards can run on Linux, OSX and Windows operating system while some boards are limited only to windows), extensible and open-source hardware and software.Īrduino UNO is one of the famous microcontroller boards of the Arduino family and is developed by. Like Arduino Mega, Arduino UNO, Arduino Nano, Lily Pad Arduino, and much more because as advance our projects are, Arduino keeps on updating its development board to keep teachers, students and other interested people updated as these boards are being used in scientific research as well as many other advanced fields of robotics and many other fields.
