What is Arduino UNO R3 Board? | Board for Rapid Prototyping
As we know arduino boards are very popular and almost every electronics enthusiast is using it. This board very useful for electronics projects. The UNO is the most used, popular and well-documented board of the whole Arduino family. Arduino UNO is an 8-bit microcontroller board with on the ATmega328P 8bit-AVR controller.
Arduino UNO is a microcontroller board based on the ATmega328P. The ATmega328P can easily be replaced, as it is not soldered to the board. The ATmega328P also features 1kb of EEPROM, a memory which is not erased when powered off. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. You can tinker with your UNO without worrying too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.
You can power the Arduino Uno with the USB connection or with an external power supply. The Arduino UNO features a barrel plug connector, that works great with a standard 9V battery.
