Arduino Uno R3 Dip With USB Cable
Arduino Uno R3 Dip overview
Arduino Uno R3 is a microcontroller-based development board. Arduino UNO and other boards can read inputs – light on a sensor, a finger on a button, or a Twitter message – and turn them into an output – activating a motor, turning on an LED, publishing something online by utilizing this R3 kit. You can tell your Arduino UNO R3 what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing.
This kit is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (6 can be used as PWM outputs), 6 analog inputs, 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 an AC-to-DC adapter or battery to start. You can tinker with your UNO without worrying too much about doing something wrong, in the worst-case scenario you can replace the chip for a few dollars and start over again.
