Grip Strength Measurement with Professor Mark Edelen.

Task
Test that the new code can be uploaded without a problem.


 * New code should make the lights glow not just red but red, yellow and green depending on the force of the grip.
 * Did not receive the actual working grip measurement from Professor Edelen.
 * So tried to upload the code to a separate arduino micro pro.
 * The code was not able to be compiled
 * Downloaded the required libraries and tried to compile it again.
 * The code was able to be uploaded to the pro micro.

Next Steps

 * Create the circuit on a breadboard to test the new code.
 * Incorporate an on/off switch in circuit, update circuit diagram.
 * Create a flowchart for the code.

Tasking
Test the improved code (provided by Professor Edelen) for the grip measurement display.


 * Purpose of improved code:to change the colors of the display. The old code lit up the display with only red LEDs. The new code should change the display so the first LEDs are green, second set yellow and the last set red.
 * The improved code changed the LED display, now bar (1-9th) are green, 10-17th are yellow/orange, and the remaining bars (24 in total) are red. The sensitivity was not affected.

Next Steps

 * Design more convenient battery access.
 * The grip and the compartment that houses the electronics is held together by a rubber band, work on the assembly.
 * Get feedback about grip measurement sensitivity, ask around (survey like).
 * Create a flowchart for the improved (new) code.

Tasking
Brainstorm assembly possibilities for the housing of the electronics and the grip, taking into consideration accessibility to the battery and durability. Work on flowchart of code.
 * Possibility of assembly:hot gluing, screwing, or a battery-cover styled assembly
 * Cons for hot gluing- permanent relatively speaking, not easy access to battery ad components.
 * Cons for screwing- edge is too small for drilling, smaller screws may not make a sturdy fit.
 * cons for battery cover style- clip on it may not bend similarly because of 3D printing. Clip needs to bend.
 * With battery cover style assembly the grip measurement device would remain in two pieces: the housing of the electronics and the grip.
 * Grip needs to be changed, old one cracked and broke after being used so much during projects day. The image only shows were the grip would be located. It is 1.5" by 1.5" by 1/8" (LWH).
 * no screwing, it should work the same way a battery cover of TI calculator works.
 * The dimensions will be adjusted to the size of the new electronic housing.


 * code may change when sensitivity is adjusted. It may only be the input values.
 * Purpose of flowchart is to better explain how the code works.

Next Steps

 * Change the grip to material that can endure bends, 3D printing plastic is too bridle to take the strain of bending that is why the grip cracked.
 * Finalize the dimensions of the battery cover to match with the new battery housing dimensions.
 * The sensitivity does not show significant difference between the orientation of the wrist, change code to be more sensitive.
 * Further refine the flowchart of the code
