3. 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

4. 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

6. 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

7. 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

8. 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

9. 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
11. 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

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