LED or light emitting diode emits a very powerful and strong light unlike the ones emitted by other types of lighting devices. In comparison to the others, this is a better choice as it uses less electricity and it lasts longer. It does not use filaments so it does not burn.
One of the most commendable uses is the flashing LED light. This can be used as an attention seeker. If one is stranded on a place, this kind of lighting can work as a help signal. People from a considerable distance can see the signal.
This is how you can make this flashing LED circuit board:
Step 1: First, you should already have an LED bulb. Go to the hardware and electronics store and find a flashing bulb LED. Choose the one that can be hooked to a 9-volt battery system.
Step 2: The next part is to attach the bulb. Connect the longer lead of the LED (this is usually the longer one) to the positive end of the battery. Connect the shorter lead of the LED to the negative end of the battery.
Step 3: You should also have the circuit board at the ready. Using a plier, insert the leads connected to the battery to the circuit board plug. By this time, you can already witness the bulb flashing.
Step 4: Now make the connection permanent. Get a 20-gauge wire and snip about 4 inches of it. Remove about half an inch of copper conductor at the ends of the wire. Prepare your soldering iron. Once it has already heated up, solder the red wire to the switch. Let it cool down before you switch it on.
Step 5: Once the soldered part has already cooled down, you can attach the positive lead attached to the positive end of the battery to the switch. Connect the negative lead, negative end of battery and the negative lead of the battery. Now you can test the connection by switching it on. The LED bulb you have installed should already blink.
Step 6: You can add more bulbs to the circuit if you want just follow the same procedures stated above.
If you purchase various colors of bulbs, you can also use this for party effects and not just to attract attention during emergency situations. This is a good way to spruce up an event. You use the smaller bulbs of various colors to make a greeting card more interesting too-
perfect for the holiday season.
