12. Problems and Outstanding Issues PROBLEMS: 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
