Simple SUDOKU Solver

The project is very easy to make with simple arduino components. Nonetheless, it has a more advanced code behind. I'm a beginner in C++, so I'm sure that my code could be improved. But it does work!

When the solver starts, move around the sudoku in the LCD panel using the IR remote as below:

• Fast Forward to move Right

• Fast Back to move Left

• Vol+ to move Up

• Vol- to move Down

• 1-9 to set the digit to the current cell

• 0 to clear the current cell

• PAUSE/PLAY to solve the puzzle

• Power to clear the entire puzzle
