mbed Application Shield
The new application shield has been designed to enable the maximum number of potential experiments with Arduino form factor development boards, keeping as much in common with the mbed application board as possible.
Where to buy
- 128x32 Graphics LCD
- 5 way joystick
- 2 x Potentiometers
- Speaker, PWM Conencted
- 3 Axis +/1 1.5g Accelerometer
- RGB LED, PWM connected
- Temperature sensor
- Socket for for Xbee (Zigbee) or RN-XV (Wifi)
1. 128x32 LCD
An example program to print text and variables to the LCD
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.
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
A frequency sweep. Press the fire button to to play it again!
5. 3 Axis Accelerometer
6. RGB LED
An example program that cycles the on board RGB LED through various colours.
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.
7. LM75B Temperature sensor
An example program to read the current temperature from the LM75B and display it on the LCD
Example program for app shield using the LM75 temperature sensor
