This shield makes it easy to build a 3D cube using 27 LEDs.

30 LEDs arranged in a 6 x 5 matrix so they can be Charlieplexed.

The Colors shield drives an RGB LED matrix using an LED driver chip that incorporates shift registers, data latches, constant current outputs and 64 x 256 gray level PWM for per color. Each channel can provide a maximum current of 60 mA.

4-digit 7-segment LED display. Features include: I2C 4 digits 7-segment driver. I2C temperature sensor. I2C EEPROM. PWM RGB LED. Blue PWR LED. Reset button. All pins broken out.

A combination of input and output devices useful for a variety of projects: 3 x slider inputs. 3 x button inputs. 4-digit, 7-segment LED display. Temperature sensor. Light sensor. Buzzer.

This shield allows your Arduino to control a door lock using an electric strike plate and one of a number of commonly-available RFID modules, and is based on the circuit described in the “RFID Access Control System” project in the book “Practical Arduino”. Supported modules include: ID12 ID20 RDM630 RDM880 HF MultiTag Features: On-board 9V….

Drive up to 8 relays from your Arduino using just 2 I/O pins. Communicates with your Arduino using I2C, so you can stack several shields together to drive 16, 24, or more outputs. I2C connections are linked by default to Arduino pins A4 and A5, but can be switched to use the R3 headers using….

16-character by 2-line display with input buttons to allow you to select menu items on the screen. Works in 4-bit mode with the “LiquidCrystal” library included with the Arduino IDE, allowing you to control the LCD with a total of just 6 digital I/O lines. Use of pins D4-D9 was selected so that it doesn’t….

For 8-bit game creation. Sprites, scrolling, stereo sound. VGA and stereo connectors.

Supports: RS485 Xbee (Xbee pro) Bluetooth APC220 SD card read/write
