How can I build an LED blinker?
LED flasher is used in many different lights and is relatively easy to assemble. Components such as a 9-volt battery, resistors and capacitors, as well as a timer chip are required. Place the necessary equipment on the cutting board and connect the electric wires with positive and negative battery terminals. Connect resistors to the ground railway and the LED blinker should work. Change the resistor for another flash frequency and always carefully process the electronics. In particular, the LED flasher is used in different types of lights. Examples of LED use include Christmas lights and flashing brands.
Progress in technology means it is easier than ever to create an LED flashing. It is also possible to control the amount of time when the light remains, as well as the frequency of its flashes. The flashing circuit can be produced using a standard 555-time chip chip. Other items of the required MS include three resistors, two capacitors, a 9-volt battery, wire cutters, wire and electric board.
The timer chip should be placed on the cutting board along with capacitors and resistors. Two of the resistors should have a resistance of 1 megaohm, the second had a 1/3 resistance of the megaohm. Connect the electric wire to the cutting board using a negative 9-volt battery terminal. Use the positive battery terminal to connect another wire to the rail on the board.
Connect the LED in the space between the Earth's rail and the resistor that has the least resistance. There are certain pins that need to be connected before both capacitors connect to the ground railway. The LED blinker should start working at this stage. The ice will flash and turn off at intervals for about half a second.
To adjust the frequency circuit Output signal, change of resistors. For example, resistors with resistance above 1 megaohm will lead to the flashing LED emitting slower flashes. Similarly, resistors with less than 1 megaohm resistance allow LEDs to flash faster.
As soon as the LED flasher is found to take it from the cutting pointNKO and place it on a plate with circuits. If you want to keep the flashed ice in place, pour it on the circuit board. Store it carefully to avoid damage.
It should be noted that each capacitor has a positive and negative side. The inability of the correct polarity causes the device failure. When dealing with electronics in general, be aware that there is always the possibility of electric shock if the device is treated.
