OverviewOverview
Project Objective:“Design and develop a multi-channel, wireless
communication system for the purpose of modifying toys for children with disabilities”
Purpose:-To afford children with disabilities the same
opportunities -To provide a cheaper alternative to current options
-Allow anyone to be able to modify toys
Representation of Prototype (Push Button
Configuration) Final Result
Multi-Switch ToyEach switch on toy-end operated by a different
switch on user-end

Problems and Problems and Outstanding Outstanding
IssuesIssuesPROBLEMS:
•Not knowing what to do = Wasting time
•Conflicting schedules
•Breaking things
•Not finishing the project
WHAT NEEDS TO BE DONE:
•Getting our modules to communicate!!!!
•Researching the different user interfaces and toy switches
•Connecting modules to the toys and switches
•Testing
•Transfer modules from breadboard to PCB
