Nov. 30, 2016 1.00 Time - Hours Done by Tibi

Contributed to testing the new load sensor with Latfi, Pov and Patrice. This generated data from a first prototype that has been prepared with more care. Test not finished yet, but we got some preliminary data.

Feature 377
Helped Scott debug the Vibration sensor on the node. we had some connection problems, it turns out that the pin 10 of the Arduino is burned.
I also helped with the code integration into the main firmware.

May 6, 2016 5.00 Time - Hours Done by Jim

Worked with Scott to integrate the communication with the Arduino Nano into the main sketch as well as wire and mount the two microcontrollers together in the "not-a-box" enclosure.
Nano firmware: https://github.com/Sensorica/Sensor-Network/tree/master/Arduino/_nano_firmware/nanoFirmware3
Main firmware: https://github.com/Sensorica/Sensor-Network/tree/master/Arduino/_firmware2
The integration is based on this code tested between two arduino's :
https://github.com/Sensorica/Sensor-Network/tree/master/Arduino/software_serial_test
We failed to achieve proper communications between the two microcontrollers and began debugging. Our process was interrupted due to the pump incident.

Issue #337
Worked on the vibration sensor with Scott at the sponsor's location.
We used a signal generator to feed data into the Arduino nano, used as a real time digital signal processing device, or DSP, to figure out some functions of this FFT library. We also figured out how to change the frequency range probed.
We figured out a few functions how to change the frequency range.
The data that we acquired was graphed here.

Issue #337
Worked with Scott on the Vibration sensor.
Installed the accelerometer on the Arduino nano, we wrote a small code for it, we tested every one of its axes, we flowed the datasheet to make sure that we were observing a good behavior, and we built understanding about hoe it functions.
We documented our findings in the main doc, linked as a resource output in this process.
After that we moved on FFT. We searched for different FFT libraries and did some thinking around the criteria that will determine our choice. Scott zoomed into one library and we installed it and started to write the firmware.
I had some problems interfacing the Arduino nano with my computer. Scott took over the communication with the Arduino and the codding. I assisted in debugging and documentation.

Link to Redmine task https://13.88.21.233/issues/432

Literature review of composite semiconductor material for load cells, to build understanding about the new load cell. Synthesis and sharing with the R&D team. Built one load cell for testing, created report with new observations and new recommendations, communicated all that to the R&D team.
This task has been approved by John in a Scrum meeting.
