Import libraryC12832

C12832 LCD with generic interface

2. Joystick

An example program for the mbed application board that uses the joystick button. The program will move a ball around the screen. If you push the joystick button, the ball will jump further to the right.

Import programapp-shield-joystick

A program to demonstrate using the joystick of the mbed application shield.

3. 2 x Potentiometers

Example that prints the pot values onto the LCD screen

Import programapp-shield-pots

Test program for mbed app shield potentiometers

4. Speaker

A frequency sweep. Press the fire button to to play it again!

Import programapp-shield-speaker

Example program to do a frequency sweep on the speaker

5. 3 Axis Accelerometer

Import programapp-shield-accelerometer

Test program for the accelerometer on the app shield

Import libraryMMA7660

Library for the MMA7660 triple axis accelerometer

6. RGB LED

An example program that cycles the on board RGB LED through various colours.

Information

The RGB LED is common anode, so that "0" is on, and "1" is off. For PWM, the closer to 0.0 the brighter, the closer to 1.0 the dimmer. use (1.0 - value) to invert.

Import programapp-shield-rgb

Example program to sweep the RGB LED through various colours using PWM

7. LM75B Temperature sensor

An example program to read the current temperature from the LM75B and display it on the LCD

Import programapp-shield-temperature

Example program for app shield using the LM75 temperature sensor

Import libraryLM75B

A simply library for the LM75B I2C temperature sensor
