Doing this enables the Uno to be more accurate when converting information from the 6 analog pins to numbers. Anything different will have to be connected to the AREF pin. 1.1 and 3.3 volts can be selected through software. A different maximum voltage for the Analog pins can be connected here and then selected through software. The maximum voltage defaults to 5 volts, but can be changed to 1.1 or 3.3 volts through software. The Uno can turn the voltage into a number between through the Analog pins. EEG, ECG, temperature sensors, light sensors, and strain gauges are examples of devices that turn physical measured information into a voltage. Six pins (or holes where pins go) are clearly labeled on the Uno. That is why a USB Host shield for the Arduino exists. The USB port on an Uno is a slave port, not the USB On-The-Go port found in cell phones. USBĪ USB mouse or keyboard can not be plugged into the Arduino as if it were a computer. Once the program is downloaded, the USB cable can be disconnected (if another power source is available) and the program will run without a computer.

The USB cable is designed to be attached to a computer so that software can be downloaded to the Arduino. This is especially true if motors are involved. At this point the individual shields may need their own power sources. Things will then work, more will be added and eventually the Uno will stop working again. The solution is to plug in a 5 to 12 volt DC in cable to the Uno. Eventually adding stuff to the Uno will cause everything to stop working. The Uno can be powered through the USB cable. Price points, competition and branding necessary for economic success.Physical feedback through lights, motors, sounds of software success.They needed to move to small standard circuit boards that are stacked on top of each other. The DIY community needed to move away from designing circuits, building unique big circuit boards and soldering chips. Surface mount chips are hard to solder.The Arduino is a success for several reasons: The goal of Wiring is to create an single board microcomputer, a programming language and an IDE that caters to artists. The Arduino was created at the Interaction Design Institute in Ivrea Italy (where Olivetti is located) in 2003 in almost one evening (24 minute video link).

The Arduino evolved out of the open source Wiring project, which was inspired by the Processing programming language.

They are popular because they give away the software development environment (C language) for free and they scale up to supporting Linux. Two popular microcontroller companies used in the DIY community are AMTEL and Microchip PIC.

Microcontrollers exist in a variety of configurations and price points starting at under two dollars for quantity one. They are found in embedded applications such as the control panel of a microwave, printer or car dashboard. Microcontrollers differ from modern CPUs in that IO, RAM, and Flash memory are imbedded in a single chip.

Microcontrollers evolved from the same microprocessors that started the PC revolution such as the Motorola 6502 and Intel 8088. The discontinued Arduino Duemilanove, replaced by the UNO in late 2010
