arduino uno schematic arduino uno datasheet

They can be configured to input or outputs, functions like using pinMode(), digitalWrite() and digitalRead(). There are total 14 digital pins on the Arduino Uno board. There are three ground pins on the board also there is a 5volt output and and a 3.3volt output for other components. There is a USB type-B Port on the board which is used to program and power the microcontroller IC also there is a separate power input port to give external voltage via regulator 7805. Here is an image showing various pinouts of Arduino UnoĬheckout here for Introduction To Arduino Uno tutorials. The Arduino open-sourced IDE drivers can be downloaded for free from it’s official website ĥ.) Digital I/O Pins: 14 (out of which 6 provide PWM output).ĩ.) Flash Memory: 32 KB of which 0.5 KB used by bootloader.ġ0.) Clock Speed: 16 MHz. it features the Atmega8U2 microcontroller chip programmed as a USB-to-serial converter. The Arduino Uno does not use the FTDI USB-to-serial driver chip. You need to simply connect it to a computer with a USB cable for programming and power it with a AC-to-DC adapter or battery to get started to run. All the necessary stuff required to the microcontroller. Also it has a USB connection, an ICSP header, power jack, and a reset button. The Uno has a 16 MHz crystal oscillator which is the heart of the board. You should also read various Arduino boards It is having 14 digital input/output pins, out of which 6 can be used as PWM output and 6 analog inputs. The Arduino Uno board is small and handy approximately 7cm long and 5cm wide.

It is simple ideal for hobbyists as well as professionals.

ATmega328p is the microcontroller used in Arduino Uno. The Arduino Uno is an open source microcontroller based development board. In this article I am going to talk about Arduino Uno it’s features and arduino uno pin out, Let’s start… The Arduino Uno board:
