Arduino Uno R3 (Original, Made in Italy)

About this product

The Arduino Uno R3 is the board most Indian schools, colleges and weekend makers build their first project on. It runs an ATmega328P microcontroller and gives you 14 digital input/output pins (6 of them PWM), 6 analog inputs and a USB-B port that both powers the board and carries your code across from a laptop.

This is the original Italian-made board rather than a clone, so the USB chip, the voltage regulator and the header spacing all behave exactly the way tutorials and textbooks describe. That matters in a classroom: fewer driver problems, fewer mystery resets, and one less thing for a teacher to debug with thirty students waiting.

Use it for line followers, obstacle-avoiding cars, LED matrix displays, soil-moisture alarms and science-fair weather stations. It accepts almost every shield and sensor module sold today, and the free Arduino IDE runs on Windows, macOS, Linux and Chromebooks.
