Thermistor

  • A simple lookup table method of getting Celcius numbers from a 10k thermistor. Code & calculating spreadsheet here: thermistor

Location

HMC6352 I2C Compass Sensor

  • Read heading from a compass sensor, using the Wire library. Here's the sketch: Learning.hmc6352

GPS

  • Arduino code for parsing data from the EM-406 GPS module, by bigengineer.
  • How to connect a Paralla* GPS module to the Arduino, and read its $GPRMC string. Tutorial translated from Igor Gonz�lez Mart�n's original Spanish tutorial. This allows you to get date, heading, latitude and longitude from the GPS module.

Nintendo and Super Nintendo Game Pads

  • See http://www.rahji.com/NESpad for libraries that handle the serial communication between one of the many types of NES or SNES game pads and an Arduino.

Bar Code Scanners and PS2 devices

  • You can hook up a barcode scanner (which simulates a keyboard) or a keyboard to the arduino. See barcode scanner

PS2 mouse interface

  • Read data from a PS2 mouse. Useful if you want to use the encoders from an

old mouse in a robot or other device. PS2 mouse interface

Matrix Keypad

  • Reads a keypad with up to 16 keys. To find out how to connect your keypad open the library file keypad.cpp and read the "PIN MAPPINGS" notes to see which pins you need to connect.

  • A cheap 4-digit seven segment led display with SPI. No decimals, though. code here: Hc4led

LCD HD44780

LCD's

Getting started: Read Heather's original tutorial. It comes with a LCD library which works great (in 8-bit mode).

Using 4-bit mode with Hitachi LCD controllers. There are now various code examples for how to talk to an HD44780-compatible LCD in 4-bit mode (in order to save arduino pins):

Relays

  • Schematic for driving DC relays using a transistor connected to an Arduino pin.

Solenoids

Servos

  • You can control up to 20 hobby servos simultaneously with the Software Servo Library.
  • You can control 2 servos, on pin 9 and 10, very precisely with the Servo Timer 1 Library.
  • You can control very large numbers of servos precisely using an external PWM chip for each group of 16 servos. See the PWM Expansion note. There will be a servo library for this part eventually.

Shields under development

XBee Shield

A shield for Arduino boards that can either act as interface between your computer and the XBee wireless network, or as a wireless port for your Arduino boards. Designed by M. Yarza in collaboration with Arduino's team. (more)

SID-shield

The shield contains a SID-emulator, programmed on an ATMEGA168 chip, some electronic components to use the ATMEGA and a small amplifier and mini-jack out. The idea is to emulate the original SID chip from the Commodore 64, cos its hard to get, and have the whole interface-abilities from the arduino. The SID-emulator was programmed by C. Haberer, see Roboterclub Freiburg for details. The shield has been designed by dusjagr/SGMK and will be posted here soon. The systems allows you to create original 8-bit sounds programmed and controlled via the Arduino board. (More about SID-emulator?)
