The Arduino Uno SMD is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, 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 adaptor or battery to get started.

The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega8U2 programmed as a USB-to-serial converter.

Questions




31 August 2015 Question by: Daniel Green | Product code: 73-4443
Q. just want to confirm, this says it includes everything needed to support the microcontroller, is a USB cable included or is that sold seperately?
A. Hi Daniel, thank you for your question. This includes only the board. The software is downloadable. The cable you need is a standard USB A to B (19-8660).

I had heard quite a bit about the Arduino board, but only recently completed my first project. I read "Getting Started with Arduino" by Massimo Banzi, and soon had an LED flashing. The project I needed it for was two slightly ambitious musical whisky-dispensing machines, which needed to flash lots of lights, play two percussive items with solenoids, and then power one of three pumps to dispense a measured liquid. My brother helped me with the code, and we got there in the end without too much difficulty. There was also an MP3 player being triggered. A MAX7219 multiplexer allowed the Arduino's outputs to control as many items as possible. The best thing was being able to quickly adjust parameters in the client's office as they made comments, simply connecting a laptop via USB and altering liquid amounts etc. as they talked. Definitely going to use more of these boards. More details and photos of the project it was used for here: www.nervoussquirrel.com/southerncomfort.html
