Sensing and Moving Module

This module controls the overall gameplay. Beginning in an idle state, the user must wave their hand in front of an IR sensor. They then must adjust the brightness of the spotlight to their desired level and toggle the joystick to begin the game! The gameplay occurs largely in the WAIT4LIGHT state, which controls posting to the TargetLEDs module to light up targets and the LED_Display_Module and PWMService to indicate game progress. The game ends in the SAD_ED state if the player unsuccessfully finds all targets, or the DISCO_ED state if the player is successful!

Spotlight Control Module

This module controls the player interaction. Beginning in an idle state, this module is but into use after a hand wave triggers a post from the Sensing and Moving Module. The then BRIGHTNESS_LEVEL_CONTROL state posts to the LED_Display_module and PWMModules to communicate with the player and react to their button-pressing interaction.

During gameplay, the MOVING state is used to react to the joystick event checker and post events to the PWMModule and move the spotlight servos accordingly. At the conclusion of gameplay, this module resets into the BRIGHTNESS_LEVEL_CONTROL mode and the user can replay if they choose.

PWM Module

This module is a simple service updating the 3 servos (spotlight two degrees of freedom and indicator servo) current angles as well as the spotlight intensity. 

Joystick Module

This module is a simple service scanning the inputs from Joystick every predefined period of time and send the values to the PWMService through global variables to get the spotlight moving when it is supposed to be in motion (during the game).
