Make a series letters from the LED
Make a series letters from the LED , Things to consider before making the sign of the LED array,
1) Use LED nodes.
2) Paint the top of the PCB with a dark color (black).
3) Note the LED specifications. In this experiment use a 5mm diameter LED nodes
that emit red, specification voltage of 3 volts.
The assembly of LED:
1) One letter composed at most 5 columns and 7 rows.
2) One column mostly composed by 6 LEDs are arranged series.
3) Then the fifth column are connected in parallel.
Here is one letter LED scheme.
Medium picture below is the lay out of the 2-letter nameplate. To make the sign 8 letter, copied from a second stay this letter.
Example of LED on the letters A and B:

2) One column mostly composed by 6 LEDs are arranged series.
3) Then the fifth column are connected in parallel.
4) Each column given the constraints, Rx, which amount depends on the number of LEDs in one column and depends also on the type of LED (in this experiment that used LED 5mm in diameter, clear with red light beam).
5) In a column consisting of 6 LEDs, Rx = 330 ohm, 5 LEDs, Rx = 560 Ohms, 4 LEDs, Rx = 680 Ohms Remember, this provision applies to 5 mm LED red light beam nodes.
6) Every letter was given FCS9013 transistor amplifier. Here is one letter LED scheme.
Medium picture below is the lay out of the 2-letter nameplate. To make the sign 8 letter, copied from a second stay this letter.
Example of LED on the letters A and B:
Value Rx in the first and the fifth column (letter A) of 560 ohms, because it consists of 5 LEDs are arranged series. Rx in the second column, third, and fourth, amounting to 680 ohms because it consists of two LEDs.
Rx first column letter B, 330 ohms. Rx second column, third, fourth, and fifth at 680 ohms.

parallel and series circuit diagrams
Some viewers hadnt clear idea about parallel and series diagram.Here you can see we can build a schema in two ways they are parallel and series.If I explain simply when you use series schema it will reduce the light of the bulb according to the number of bulbs but when you use parallel schema diagram it will not reduce the light of the bulb but it will drain your battery speedly
