The Arduino Uno, the successor to the Arduino Duemilanove, is a microcontroller board based on a surface-mounted (SMD) ATmega328 AVR microcontroller. It has 20 digital input/output pins (of which 6 ...

In ARDUINO we have 20 I/O pins, so we can program 20 pins of UNO to be used as either input or output. Although there are more pins on ATMEGA328P controller than on UNO, this is because while ...

Arduino stands for beginner-friendly and fast development of embedded projects. Playing around with Arduino boards is fun, but not the most efficient way to expand your knowledge. Elektor has ...

Arduino UNO is quite easy to program. As most of you might have known that in order to program a microcontroller one need to write the code in the editor, and then compile that code in the compiler ...
