The arduino uno pinout guide includes information you need about the different pins of the arduino uno microcontroller and their uses: power supply, analog and digital pins and icsp the guide also discusses different communication protocols used by the arduino and a detailed diagram of the arduino uno board. Pin diagram of arduino uno r3. Arduino uno is a microcontroller board based on the atmega328p ()it has 14 digital input/output pins (of which 6 can be used as pwm outputs), 6 analog inputs, a 16 mhz ceramic resonator (cstce16m0v53-r0), a usb connection, a power jack, an icsp header and a reset button.
pin diagram of arduino uno r3
The arduino uno is arguably the most popular arduino board currently available this arduino uno pinout diagram reference will hopefully help you get the most out of this board: the arduino uno board is divided into digital pins, analog pins and power pins there are pins with secondary functions as listed below. Each of the 14 digital pins on the arduino uno can be used as an input or output, using pinmode(), digitalwrite(), and digitalread() functions. they operate at 5 volts. each pin can provide or receive a maximum of 40 ma and has an internal pull-up resistor (disconnected by default) of 20-50 kohms. in addition, some pins have specialized functions:. The arduino uno is a microcontroller board, based on the atmega328p (for arduino uno r3) or atmega4809 (for arduino uno wifi r2) microcontroller by atmel and was the first usb powered board of arduino. the atmega328 and atmega4809 comes with built-in bootloader, which makes it very easy to flash the board with your code..
