 Problem:
 Stale beans due to the long period of time between
roasting and brewing
 Separate coffee making components further
increases length of overall process and consumer
inconvenience
 Proposed Solution:
 Create system to shorten time from fresh beans to
coffee
2 of 16

 Objective:
 To integrate and modify off-the-shelf components
through use of hardware programming
 Deliverable:
 Create a 3-in-1 coffee system controlled by
Arduino microcontroller

1. Beans are roasted for 4 minutes, then poured into
grinder after sitting for 24 hours
2a. Roasted beans are then ground for 10 seconds;
ground beans are then shot into French press
2b.The water heater heats the water, dispenses it into
the French press
3. The water and ground beans sit in French press for
four minutes before grounds are separated from
newly brewed coffee
4. Coffee is poured out of French press through the
spigot, and into a cup

 Input: Fresh green coffee beans
 Process:The roaster is mechanized
using a pulley system powered by
a motor that:
 Output: Uses a spool to pull down the
top of the roaster until the beans are
poured in to the grinder
 Goes in reverse to unwind the
spool, and return the roaster to its
original state

 Input: Roasted beans
 Process: Grinds beans
coarsely
 Output: Grounds shoot into
French press through pipe
 Input: water
 Process: Heats water with
use of bubble valve
 Output: Pours water into
French press through tube
7 of 16

 Inputs: water and coffee
grounds
 Process:
 Coffee grounds and water sit
together for 4 minutes
 Plunger pulley system
activated by DC motor and
separates grounds from
water
 Spigot opened by servo
motor and fresh coffee
poured into cup 8 of 16

 Mechanically integrated and modified an off-
the-shelf popcorn popper, grinder, coffee
maker and French press
 Hardware programming was not successful
 Limit switches were not utilized due to technical
difficulty in implementing them in the circuit and
design layout
10 of 16

 Study circuits using limit switches
 Utilize a printed circuit board instead of a
bread board
 Fix the Arduino microcontroller code
