A minor typo in Row Column Scanning Tutorial Code
Today at 13:44:01 | Modify | Remove I think there is a minor typo in Row Column Scanning Tutorial (/en/Tutorial/RowColumnScanning) code.
In that page, the array of row pin numbers is defined as follows:
const int row[8] = {
2,7,19,5,18,12,16 };
The array of 8 cells has only 7 items and pin number of 5th row is lost. The definition should be:
const int row[8] = {
2,7,19,5,13,18,12,16 };
I hope that you will be able to correct it. Thanks.
