Week of Febuary 11
Whole group: ~3hrs~: worked on design flaws, must return some parts. discussed compilation of parts
2/14 Cj Wilson: ~1.5 hr~ Sketched design for bottle holders and researched code for the pumps now on trello.
2/17/19 Whole Group: Flow Chart for arduino pins
Goals for Next Week:
Complete arduino blinker

3d print night light from different source
A/D converter testing
Week of February 18
2/18/19 CJ and Weronika: ~1 hr~ made external LED blink, team meeting
2/22/19 CJ ~4 hrs~ soldered the battery back onto the nightlight and put it together. Checked if Pump worked attached to 12V, connected to driver, pumps water, created code to pump water for certain times.
2/24/19 Cj~ 2hrs~ tested the photo resistor, need to do further testing with stronger LEDS. Tested with plastics cups and water. Results: slight change but need to confirm to see if they are drastic enough and consistent for accurate readings.
two yellow: with water~ 12 without water~12.5
two blue: with water~ 11 without water~ 15 blue light is better
2/24/19 Tom ~2hr~ Made code diagrams and worked on code
Goals for next week:
Start coding for drinks
Test weight sensor
Figure out our display
Week of February 25th
Tom ~ 2hr~ Changed code chart and worked on lcd display
Cj~1.5hr~ 3/1 Worked on Photoresistor, stumbled upon the idea of using a sonar. did some basic research on how to hook up sonar. Tested with plastic and glass
Glass with water--2.8kiloohms Glass without water--2.3kiloohms
Plastic with water--3.1kiloohms Plastic without water-- 2.6 kiloohms
Cj~2.5hrs~Hooked up sonar and coded it to sense when an object is 6 inches away. once it is atleast 6 inches away an LED goes from green to red. I think that this will be a more accurate way to tell distance. I did test with water and it seems to work.
Goals for next week:
Have screen menu coded
Get bottles and create case for them
Test weight sensor
More testing on sonar
Startcode for motors
hook up relay with motor
Test the photoresistor with voltage divider
Week of March 4
Whole Group~1hr~ team meeting. discussed deliverables
Tom ~3hr~ Got LCD display working 
CJ: Ultra sonics vs Light Resistor, get holder modeled, How is the container going to look
Weronika: Get weight sensor working (if it comes in time), get the pump to stop pumping when a threshold is reached. Get motor and relay working the arduino can turn on the relay that will allow the motor to turn on.
Tom: Program LCD to be able to select thru different menus, feed back from LCD to arduino
Will: Show team how to use the 5V relay module, ref voltage
Cj Wilson ~2hrs~ 3/7/19
tester with LED BLue and 220k resistor:
with water: 835
without water: 940
learned about analog reference, Reference voltage and the voltage divider. Attempted to calculate resistance need to get a factor of ten difference but every approach gave us negative numbers for the resistance. Will design case for both and discuss further with Jim.
Tom~1hr~ 3/7/19 Worked on LCD and got return to work for first drink.
Cj~longer than it should have been~ 3/10/19 Awkwardly asked flight attendant for bottles after they did concessions for everyone mission accomplished!
Designed bottom and tops for bottles
Tom ~1.5hr~ 3/17/19 Added another failsafe to LCD Display
Tom ~1 hr~ 3/17/19 Cleaned up LCD and started to write a check method
Weronika ~2hr~ 3/14/2019 Connected load cell components, found code and measured weight with arduino. Need to find mass of known weight to find calibration factor (-270) and change units from lbs to grams. Calibration code and scale code on github
Weronika ~3hr~ 3/17/2019 Connected relay, two drivers, three pumps and arduino, need to troubleshoot
Weronika ~4hr~ 3/8/2019 Got pumps to alternate running on a timer (code on github), began working on code to make pumps run until threshold and then switch to next pump. Load cell is best used when mounted. Changed load cell units to grams.
Pumps alternating on a timer
Week of 3/18
To Do this week:
Meet with Jim with reference on Wednesday?
- need to meet with Weronika
Tom~2 hr~ 3/18/19 Finished LCD and worked on check supplies method
Cj WIlson~ 1 hr~ 3/18/19 worked with tom on screening.
Weronika ~2hr~ 3/19/19 rewired relay to use one driver
Tom~2hrs~ 3/19/19 Worked on weight sensor and empty method
Cj Wilson~2hrs~ 3/20/19 Discussed with Jim next steps for Photoresistor. Calculated the ideal resistor by taking the voltage equation and maximizing it. The ideal resistor we need is 11.8k. Created the Arduino code for the Photoresistor to test if bottle is empty. I think.
Tom~1hrs~ 3/19/19 Worked on weight sensor
Weronika ~1hr~ with Will, modified arduino code to switch relay upon input. Cj, Will and I filmed this lovely video:
Relays switching upon 1, 2, 3, 0 input to serial monitor, with pump 3 pumping water. Code on Github.
