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 ...

Now let's look at the pinout for the Arduino Uno R4 WiFi development board. As you can see it is very similar to the Uno R3 development board but with each pin with more functions. It also provided ...

Arduino Uno pinout. There are two kinds of pins: GPIO and power pins. GPIO pins let you process inputs and outputs. By default, all Arduino pins are inputs. On the other hand, power pins are meant for ...

I myself own an Arduino Uno R3 and found that it can simplify my projects development and microcontroller programming, but sometimes I need to know the Arduino pinout. That is why I have written this ...

The pinout diagrams are simple, but they're easy to read, and especially helpful for beginners. You can print them out full size so you can set your Arduino Uno, ATMega, or ATTiny right on top for ...
