wishes for the project. Figure 3.
Prepare matrix board, any space for that matter, follows:
● Turn the matrix board that manufactured straight edge the
top and left-hand side
● Use felt tip pen mark the holes groups five along the top
edge and down the left-hand edge shown Fig.
The pins can then inserted required.7. The position of
point 4:3 would holes from the left and holes down.

To set the grid reference, count along the columns the top the
