Scriptronics Arduino Uno R3 Development Micro controller Board ATmega328P with L293D Motor Electronic Components Electronic Hobby Kit

he A_rduino Uno is one kind of microcontroller board based on ATmega328, and Uno is an Italian term which means one. A_rduino Uno is named for marking the upcoming release of microcontroller board namely A_rduino Uno Board 1.0. This board includes digital I/O pins-14, a power jack, analog i/ps-6, ceramic resonator-A16 MHz, a USB connection, an RST button, and an ICSP header. All these can support the microcontroller for further operation by connecting this board to the computer. The power supply of this board can be done with the help of an AC to DC adapter, a USB cable, otherwise a battery. This article discusses what is an A_rduino Uno microcontroller, pin configuration, A_rduino Uno specifications or features, and applications. What is A_rduino Uno ATmega328? The ATmega328 is one kind of single-chip microcontroller formed with Atmel within the megaAVR family. The architecture of this A_rduino Uno is a customized Harvard architecture with 8 bit RISC processor core. Other boards of A_rduino Uno include A_rduino Pro Mini, A_rduino Nano, A_rduino Due, A_rduino Mega, and A_rduino Leonardo.
