Just realized how challenging the feedback/drawing coding is going to be for this project. Need to implement some kind of control theory – yikes. The hurdles to overcome are as follows:
- With only eight LED indications there are only a total of 16 directions I can direct the user.
- Need to break the drawing into line segments which are navigable for the user without creating erratic/confusing/contradicting LED directions.
- If the user deviates off course, the path needs to be corrected and recalculated.
Here are some photos. Enjoy.
