Steps to make an LED Flashing Light Bar

[yunaoled]

An LED flashing light bar is really a bar having a row of LEDs that start flashing at one finish from the bar and finished in the other. The pleasing pattern of lights that results makes them bars helpful as adornments for vehicles, parties, and home bars. You might construct your own flashing light bar in your own home, saving cash while customizing the LED colors.|LED SpotLight

1

Place the LEDs in to the 40-pin nick socket. Space the LEDs to ensure that you skip every second set of electrical sockets. This can provide the lights room. Invest the negative leads on a single side, and all sorts of the positive leads alternatively.

2

Switch on the soldering iron and allow it to warm up. Place the LED socket in to the holes in the heart of the little circuit board. Touch the end from the iron to every lead from the socket by having an LED inside it whilst touching charge using the tip from the solder. Once the solder touches to the lead and board, take away the iron.

3

Remove 1/2 inch of insulation from each finish of each one of the wires using the wire strippers. Put the finish of among the red-colored wires in to the small circuit board alongside an LED's positive lead. Touch the solder and also the soldering iron to both wire and also the lead simultaneously to solder them together.

4

Solder another red-colored wires towards the positive leads and also the black wires towards the negative leads. Tape the wires towards the board using the electrical tape. Bunch then together some distance in the fringe of the board and tape them right into a bundle. You have a bar of LEDs installed on a little circuit board having a cable of wires being released of the foot of the board.|MR11 LED Spot Light

5

Place the 555 timer nick in to the 8-pin socket. Place the 4017 counter nick in to the 16-pin socket. These electrical sockets will isolate the chips from warmth while soldering their leads. Place the chips in to the other perforated circuit board and solder them into position.

6

Place the resistors in to the circuit board alongside consecutively. Solder all of the leads of one for reds of this row together. Solder a jumper wire to every finish of the row.

7

Solder the bare finishes from the red-colored wires to leads through 9 from the 4017 nick. Solder each black wire to among the unconnected leads from the resistors.

8

Solder the unconnected finishes of these two jumper wires towards the "Gnd" leads of both 555 timer and also the 4017 counter. Solder a jumper wire in the "Out" lead from the 555 towards the "Clk" lead from the 4017. Solder another jumper wire between your "RST" lead from the 555 and also the "VDD" lead from the 4017.

9

Solder jumpers between "ClkEn" and "Rst" and between your "Rst" and "Gnd" leads from the 4017. Solder jumpers between "RST" and "VCC," between "Disch" and "Thresh," and between "Thresh" and "Trig" around the 555.

10

Solder the leads from the capacitor towards the "Trig" and "Gnd" leads from the 555. Solder the leads from the 1 megohm resistor towards the "VCC" and "Disch" leads from the 555.|MR16 LED Spot Light

11

Solder the negative wire in the battery holder towards the "Gnd" lead from the 555. Solder the positive wire from the battery holder towards the "VCC" lead from the 555. Place the battery in to the battery holder and also the flasher will begin to work.
