Hardware Preliminaries

1> Inventory the materials prior to start of assembly.
2> Secure appropriate pin layout (MEGA256 Arduino or Arduino Uno) for reference.

2.1> Arduino Mega256: https://www.sparkfun.com/products/11061

2.2> Arduino Uno: https://www.sparkfun.com/products/11021

2.3> Place Arduino board on a solid insulated flat surface.

2.4> Without connecting the Arduion to USB or power yet, continue to "build".

2.5> As each Shield SubAssmebly is completed, mate it to the Arduino board.

2.6> Once all Shield SubAssmeblies have been mated to the Arduino

2.6.1> Connect the Arduino to the PC via USB.

2.6.2> Power-on the PC.

2.6.3> Verify that the Arduino has a Power-On status LED visble.

2.6.4> Power-off the Arduino USB and proceed with the build of the hardware..

3> Stepper Motor Control Shield Subassemblies:
3.1> Adafruit Motor Sheilds:

Two Adafruit Motor Shields v2.3 are required to control the stepper motors. The two shields provide four axes xyza CNC capability of the Chickadee Ventilator Simulator Platform. The bad news is that their require a corresponding set of five stacking headers per shield to be "soldered". Adafruit provides a good set of instructions on how the order the headers and perform the soldering operation.

3.1.2> Stacking Headers: https://www.adafruit.com/product/85

3.1.3> Solder the five Stacking Headers to each Adafruit Motor Shield per 3.1.1

3.1.4> Designate one of the Adafruit Motor Sheilds as AMS1

3.1.4.1> Refer to AMS1 Wiring

3.1.4.2> Orient the AMS1 shield as shown in 3.1.4.1.

3.1.4.3> Connect the battery cable and jumper.

3.1.4.4> Kludge the connection between Connector1 and AMS1.

3.1.4.5> Kludge the connection between Connector2 and AMS1.

3.1.4.6> Insert the AMS1 as the first shield of the Arduino

3.1.5> Designate one of the Adafruit Motor Sheilds as AMS2

3.1.5.1> Refer to AMS2 Wiring

3.1.5.2> Orient the AMS2 shield as shown in 3.1.5.1.

3.1.5.3> Connect the battery cable and jumper.

3.1.5.4> Create the solder brdge between pads

and in this detail image.

3.1.5.5> Kludge the connection between Connector1 and AMS1.

3.1.5.6> Insert the AMS2 as the second shield of the Arduino

3.1.6> As needed see reference cited below for Stepper Motor assistance

3.2> Proceed with the build of the hardware.

4> Seeed SD Card Shield

4.1> The Seeed SD Card Shield does not require any further aeembly. Just install an SD Card to make it functional. Note the Seeed Card Shield does not have a Power-on Status LED.

4.2> Insert the Seed SD Card Shield as the third shield of the Arduino

4.3> Proceed with the build of the hardware.
