This is a Simple LED Matrix Horizontally Circuit Diagram. LEDs provide a befitting way to electronically display information. whereas the seven-segment LED brandish, organized in the pattern of the digit 8, is common, it does not permit the brandish of some alphanumeric individual features. A 5×7 commanded matrix permits the display of all ASCII individual features, as well as graphics shapes.

The schema in this conceive concept displays an unconventional way to use a 5×7 LED matrix.You can use a conceive encompassing a set of 5×7 commanded flats without altering any thing in the schemary, except for the arrangement of the commanded units.

 Using one 5×7 LED matrix, or N units, horizontally instead of vertically allows the display of two characters, or 2×N characters. The minimum pattern for lowercase and uppercase letters requires only a 3×5 LED configuration, except for the letters M and m, which require at least a 5×5 LED configuration and need a dedicated subroutine.

The schema in Figure 1 uses an 8-bit, 18-pin PIC micro controller and a decade counter to drive one or two 5×7 LED units to provide a display module of two or four digits. The schema uses a small push button switch to increment the counter. By default, the schema works in high-brightness mode. If you press the push button during power-on, the schema works in low-power mode.
