Description
UNO R3 board is a microcontroller board based on ATmega328. It has 14 digital input/output pin (six of them can be used to PWM outputs), 6 analog input pins, a SCL pin, a SDA pin, a 16 MHz quartz crystal, 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. Downloading program by UNO board is simple and convenient. You can use various components such as: LEDs, buzzers, buttons, resistors, and so on with UNO R3 board to make all kinds of interesting works by programming.
