18. Actual Spring Schedule Week LauraSteven 1Reviewed Specs for Photo Diode, Learn to use Keil PK51 Package Looked at Current to voltage Converter 2Set up simulation for I to V converter Learn to use Keil PK51 Package 3Finished simulations for both I to Begin coding weapon software V converters and started building circuits 4Finish building circuits and test themInterface weapon software and laser systems

19. Conclusion u Software - Working on weapon software u Hardware - Working on laser receiver for the weapon u Many challenges to overcome to finish weapon u A little behind schedule
