Innovations in technology and Salesforce now allow individuals to make almost any object "smart" or solve any business problem when placed in capable hands. The Salesforce Studio at Deloitte Digital wanted to make their traditional foosball table "smart enough" to track player statistics and data, ultimately creating a ranking and bracketing algorithm capable of pairing like-skilled players. Join us to see how we've combined Internet of Things technologies, such as Arduino and Raspberry Pi, with the Force.com Streaming API and web services to create automatic game scoring and data logging, and present it in a near real-time, bootstrap-enabled, HTML5 scoring page. The game doesn't stop with game play. Users can interact and report on player data and statistics through Wave and out-of-the-box Salesforce!

Jeff Kimble works with top talent and senior leadership in the Deloitte Salesforce Studio in Denver, CO to create cutting edge and innovative solutions in a best-in-
breed environment. He has helped build, design, architect, and lead projects across an array of verticals. Jeff’s work with the State of Colorado at the Dept. of
Transportation Division of Aeronautics won the state national acclaim. He has also worked on or architected myriad other systems for numerous other states
including other Colorado departments, the State of TX, and the State of MI.
Jeff has worked as a Salesforce consultant for the past four years and an architect for the previous two. Before working in the Deloitte Studio, he consulted for other
leading Salesforce-specific consultancies including Vertiba and NTT Centerstance. He holds many Salesforce certifications including Administrator, Advanced
Administrator, Developer, Sales Cloud Consultant, and Service Cloud Consultant and is a green belt in the Salesforce Wave Analytics Cloud.
Jeff grew up just outside Cleveland, OH before joining the Army and serving on the U.S. Army Honor Guard at Arlington National Cemetery. Following his service,
he attended Harvard University with a concentration in International Relations before finally landing in Denver.

Welcome!

4. The Genesis of Project: Foozlander

5. Never a marketing scheme
Curious people being curious
• Didn’t know HOW, but knew we could
• Continued (and continues) to evolve
“Wouldn’t It Be Cool if…”

6. Managed like a “regular” project
• Developed user stories
• JIRA: “As a foosball player, I should see the score.”
• Broke them down into sprints, enhancements, and backlog
• Used stories to start giving us direction and researching
Break it Down!

7. Still a learning experience
• Burned out some devices
• Needed stronger documentation and wiring schematics
• Spare parts are good parts!
Other Major Lessons:
• Large “immaterial” cost to physical failure
• Not like coding where one can revert
• Many parts have weeks of lead time
But Still a Little “Wild West…”

8. Translating into Tech
From idea to inception

10. Never Let Them See You Sweat!
Arduino
Single-task orientation
“Least capable”
Raspberry Pi
WiFi!
Linux!
Can handle many tasks
Still kinda slow…
Know your limits and play to your strengths
IR and RFID Sensors

11. Building the (Virtual) Bridge to Salesforce
C (Arduino)
• Detect IR sensor beam break via
voltage drop
• Publishes Sensor Data via General
Purpose Input Output (GPIO)
Know your limits and play to your strengths

12. Building the (Virtual) Bridge to Salesforce
Python (Raspberry Pi)
• Calls out via REST
• Simple Salesforce Library
• Consumes GPIO for Arduino
• NFC Library for RFID
Know your limits and play to your strengths

13. Boils Down to Three Lines of Code…
1: Import library
2: Create connection with SFDC
3: Call Web Service
Raspberry Pi Code Written in Python
1: Import library
## Import simple_salesforce library
from simple_salesforce import Salesforce
2: Create connection with SFDC
## Setup the SFDC Connection
sf = Salesforce(username=uname, password=pwd, security_token=tkn,Sandbox=True)
3: Call Web Service
##sf.Goal__c.create({'Name':'GoalTeam1','Foosball_Match__c':matchId,'Team__c':team1Id})
sf.Sensor_Data__c.create({'Table_Id__c':tableId,'Sensor_Id__c':’Black’,'Sensor_Value__c':'1'})

14. Strongest Skillset
• “We obviously got this.” – Victor “The Animal” Abraham
• Less obvious lesson: “an expert carpenter with a decent hammer can build a better boat than a rookie
carpenter with best hammer money can buy”
More computing power at scale
• Heavy lifting offloaded
• Adding sensors and more calls out has less impact on hardware setup
Turns out we know a few SFDC developers…
…So Make Salesforce Do It!

15. Streamline sensor data
• Sensor call is only two data points: Sensor Name, Sensor Value
• Example: Goal is Scored
Sensor Name: BlackGoal
SensorValue: 1
• Can be anything! (Name: DeliveryProdLineFault & Value: 1; Name: SpinDetector & Value: 1)
Weigh Function Against Complexity
• Streaming API = “realtime scoring”
• Single daily batch call simpler when applicable
Always “Think Big” when developing system architecture
Stay Three Steps Ahead of the Other Guy!

16. Next-Level Insanity
Sometimes it’s entirely appropriate to kill a fly with a sledge hammer

17. Novel Findings
Old table had statistically significant bias
Sun triggered false positives (environmental factors)
<<Insert graphs from Wave>>
Visualizing Player Data using Wave Analytics Cloud

18. Based on Glicko2
Uses levels of deviation
Scoring floor of 350
“Starting” score of 1500
Player Ranking

19. In Summary

20. Infrastructure
• Keep sensors and connected devices as simple as possible
• Account for growth, even if you don’t think it will happen
Play to Your Strengths
• Use your skills to break down new concepts into manageable pieces
• Offload heavy lifting to SFDC
Think Bigger
• Basic understanding opens understanding for a vast array of connected devices
• Never stop questioning, you’ll be surprised what you find!
In Summary…

21. Thank you
