About Arduino Uno (ATmega328P, 8-bit)
The Arduino Uno Rev3 is a widely used microcontroller board based on the 8-bit ATmega328P microcontroller. It operates at 5V and features 14 digital input/output pins (6 of which can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, and a power jack. It is programmable via the Arduino IDE. The board includes everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery. This board is ideal for learning electronics, prototyping IoT devices, robotics, and home automation projects. Its open-source nature and extensive community support make it the go-to choice for makers and engineers in India.
