E Shore Technologies - Online Robotic Center

Under this project, I will demonstrate a very simple input and output control for FEZ Panda II. Required components for this project:

• FEZ Panda II (http://www.e-shore.com.my/homepage/eshop/fez-panda-ii)
• ADP01 [optional] (http://www.e-shore.com.my/homepage/eshop/arduino-development-platform-v1)
• Breadboard (http://www.e-shore.com.my/homepage/eshop/small-self-adhesive-bread-board)
• Some LEDs, push buttons and resisors

Prepare your FEZ Panda II and your PC, make sure all the required software is install in your PC including the drivers, dotNET Micro Framework, Visual Studio and etc. Follow this link (http://www.e-shore.com.my/homepage/dotnet-micro-framework/87-fez-panda/204-getting-started-with-fez-panda-ii.html) for the Getting Started for FEZ Panda II. Connect the 5V and GND pin from FEZ Panda II to breadboard for easier 5V and GND pin access on the breadboard.

Connect 2 x LEDs to the FEZ Panda II (D10 and D11), series with 220 Ohm resistor, active high.

D-pad is short form for directional pad which is usually a thumb-operated directional control with one button on each direction.  For me, it is a very good input for a microcontroller system that allows the user to navigate through various menu and setting for a microcontroller system. Under this article, I will discuss on a very cheap DIY D-pad Module for microcontroller system.

Click on the link above to jump to product page of Rainbow LED Ring V2. Rainbow LED Ring or RGB LED Ring is an Arduino controller that uses ATmega168 and it comes with bootloader for Lilypad Arduino w/ ATmega168. This means that this Rainbow LED Ring can be use as an Arduino controller and we can write its coding using Arduino IDE.

Required Supporting Item(s)

The only item required for the Rainbow LED Ring to function is FTDI USB to Serial Converter & Breakout (http://www.e-shore.com.my/homepage/eshop/ftdi-usb-to-serial-converter). Unlike normal Arduino controller, Rainbow LED Ring doesn't come with onboard USB to UART converter for the communication from PC to ATmega. Therefore we'll need an external USB to UART to upload code from Arduino IDE to Rainbow LED Ring.

In this project I am going to add in IR Remote Control (Infrared Kit) to the previous 2 Wheels Robot Platform (link).

Hardware

The first step is to mount the IR Receiver Module to the platform. You can use your creativity to do this. For me, I mount it at the front side of the platform.

This is an Arduino Shield but its size is much bigger than any of the Arduino main board. The Arduino Project Shield (APS01) is our latest product which provide you an “everything ready” shield/platform to start any Arduino related project conveniently in no time.

Why we say that the shield is everything ready to start a project? This is because the shield:

• Support most of the Arduino Main Board – Arduino Uno, Arduino Duemilanove, Arduino Mega and Arduino Nano
• Support most FEZ .net Micro Framework Development Board – FEZ Domino, FEZ Panda and FEZ Panda II
• Consists of many onboard I/O expansion ports for direct sensors connection
• Consists of 4 external push buttons for input usage
• Consists of a parallel LCD port for LCD module as user interface
• Consists of a 2x8 LCD port for 2x8 LCD module as another option of user interface
• Consists of servo power input port, I2C port, external input power port and UART port
• Consists of a prototyping area for extra circuit development or just place a breadboard for non-soldering circuit development
• library to read the push button and control the LCD module is provided
• Capable of staking another Arduino shield
• provide a nice looking and tidy platform for your Arduino project

A picture tells a million words. Lets see more pictures on what APS01 can do for you.

I/O expansion ports with clear label

Breadboard/Protoboard is a great way to easily setup an electronic project. But, sometimes, some damaged Breadboard will makes electronic project no fun, that the Breadboard can’t perform or connect our circuit in the way it should be. Under this article I will show on the steps to repair or service your Breadboard.

Under this article, we will be controlling 8 LEDs using Shift Register IC 74HC595 (Quick Reference for 74HC595 here).

74HC595 is a Shift Register IC, that we can use it to expand limited Microcontroller output pin. We can use minimum of 3 output pin from Microcontroller to control the Shift Register IC (DS, SHCP and STCP) and we can have total of 8 output pin from from the Shift Register IC. In the other words, it is a serial (3 pin) to parallel (8 pin) converter that allows us to expand output pins from 3 pin to unlimited output pin. Connecting these Shift Register IC in series we can have more that 8 pin output, for example, using 5 x Shift Register IC, we can expand the output pin from 3 pin to 40 pin (5 x 8 pin). We will never be out of output pin anymore!

The title describe almost the whole project, we will be using Arduino Duemilanove to read the analog value from Triple Axis Accelerometer MMA7260 and display the output on LEDs.

The Triple Axis Accelerometer MMA7260 is a small module, that output 3 Analog value representing the accelerometer reading in 3 axis, x, y and z. You can see the x, y and z label on the bottom right of the accelerometer module. There is also a 2 way jumper on the left side of the module, where you can configure the g reading for the accelerometer according to your usage. The complete table for the configuration is show below. Full datasheet for the accelerometer can be found here.

Please take note that to set the jumper to 0, set the jumper to “up” position (like how it is shown in the image above). The setting for the Accelerometer above is 00, which is 1.5g-Range, and 800mV/g Sensitivity. This setting will be use for this project.
