5. CHALLENGES
1. ELECTRICAL COMPONENT
➔ Enabling Arduino to accurately
read input from the load cell
➔ Given the limited perforations on
the breadboard, fitting the
electrical wires and the load cell
amplifier
➔ Prevent the electrical wires from
disconnecting or touching
6. CHALLENGES
3. Software Component
➔Using the Arduino software
➔Calibrating the angles of the servo
motor to the appropriate bins based on
the weights of the different coins
2. Mechanical Component
➔Attaching the servo motor to the base
of the robotic model
➔Dropping several coins on the scale at a
time
➔Turning the coin holder that receives
the coins

9. BACK TO OUR THEME: USEFULNESS
Let’s recycle our idea of sorting objects
based on their weights…
For example… We can sort…
● Bottles, Cans and Jars…
● Metal, Plastic and Glass…
Benefit: Promoting and facilitating
environment-friendly behaviors
10. POSSIBLE IMPROVEMENTS TO OUR
PROJECT
Mechanical Component
➔Design a mechanical model that can sort multiple objects at a time versus one object
at a time
Electrical Component
➔Improve the electrical system to prevent short circuit/circuit interruptions
Software Component
➔Implement a program that optimizes movements of the sorting mechanism (and
perhaps allowing efficient energy use)
- The basic principles of your project. (What is it? What is its function?)
• Details about the design process. (Did you run into any challenges on the way? If so,
then how did you overcome them?)
• A brief overview of how your project works. (What is the basic flow of information,
from input to output?)
