Quick Answer
A 5 × 7 matrix has 35 LEDs in 5 columns and 7 rows; a character is shown by lighting one column at a time with its row pattern, fast enough that the eye sees a steady image. Students write the character tables and the scanning routine in C and send them from the PC parallel port. The module works with the Computer Interface Trainer, which provides the 25-pin parallel link and the 5 V and 12 V supplies; please confirm at quotation whether the base trainer is included.
