Post-0.3.0: migrate arduino-repo sketches to scoped (enum class) enums

[jonfroehlich]

Type: post-0.3.0 follow-up · Where the work happens: the makeabilitylab/arduino repo (not this one)

0.3.0 (PR #8) makes the four public enums enum class (ShapeType, PointSymbol,
JoystickYDirection, GraphPrimitive). Because the arduino repo consumes this
library via a directory junction, once 0.3.0 lands those sketches must qualify any
bare enum values, e.g.:

• JOYSTICK_Y_DIR = RIGHT → JoystickYDirection::RIGHT
• PointSymbol symbols[] = { CIRCLE, SQUARE } → { PointSymbol::CIRCLE, PointSymbol::SQUARE }
• const enum JoystickYDirection ... → drop the enum keyword

Until then, those sketches will fail to compile against the updated library.

Candidate sketches (include a migrated header)

• OLED/AnalogDigitalJoystickTest, OLED/AnalogGraphMultipleInputs,
  OLED/AnimatedSpriteExample, OLED/BallBounceObjectOriented, OLED/CollisionTest,
  OLED/FlappyBird, OLED/MoveBallJoystickTest, OLED/Pong
• Sensors/Accelerometers/LIS3DH/{AccelBall, AccelGraphMultiValue, AccelGraphSingleValWithClass}
• Serial/FlappyBirdSerialIn

(Not all reference bare enum values — joystick + graph-symbol sketches are the ones that do.)

Find the exact spots

cd d:/git/arduino
grep -rInE '\b(RIGHT|LEFT|UP|DOWN)\b|PointSymbol|\benum (JoystickYDirection|ShapeType|PointSymbol|GraphPrimitive)\b' --include='*.ino' .

Also remove any lingering #include <LineGraph.hpp> / MultiValueScrollingLineGraph
usage (that header was deleted in 0.3.0).

Do after: PR #8 is merged and the library updated. Verify each with
arduino-cli compile --fqbn arduino:avr:uno <sketch>.
