These topics cover the hardware and software setup required to connect an Arduino device with a variety of electronic parts, chips and devices. A related topic not covered under this section is the shield, boards that plug directly into an Arduino's pin layout. Information on the creation and use of specific shields belongs in that section. Information on shields in general and their creation belongs here. See here for a table of shields and the Arduino pins they use. Arduino has limits on how much current can be sourced or sunk by its I/O pins. When interfacing with hardware you need to be careful not to exceed these limits. For details see ArduinoPinCurrentLimitations. In general, for AVR based Arduinos, do not exceed 20 mA per pin. In particular, do NOT directly connect LEDs to Arduino outputs! Always use a series resistor (220 ohms is a good value). Examples and information for specific output devices and peripherals: How to connect and wire up devices and code to drive them.

See also the pages devoted to the Dallas One-Wire MicroLan, I2C and Ethernet. They enable you connect additional output (etc.) devices across networks controlled by the Arduino. The trouble of controlling a network is repaid if you need to connect many outputs (and/ or inputs), or if your actuators / sensors are not close to your Arduino. The UNO and Mega2560 use an ATmega8u2 or ATmega16u2 to provide the USB interface to the Host PC and it is programmed with USB to serial firmware. The firmware on the ATmega8u2/16u2 can be replaced to turn the UNO or Mega2560 into a different USB device such as a Keyboard, Mouse, or MIDI device. This section has links to different USB firmware resources. The coming Arduino Leonardo has USB support built into the the processor, removing the need for the FTDI or the ATMega8u2/ATMega16u2 to communicate with a host PC and the Arduino 1.0 IDE has partial support (written 22/2/12) for keyboard and mouse interfaces. The Micro has USB support as a Keyboard and or Mouse.

This can be used to play the Les Paul and Robert Moog Google Doodles as an example. To use more USB HID functions like Gamepad or Media keys see HID project above.
