 A Mini LED Flasher you would love to assemble

You might have seen big photo frames decorated with LED lamps glittering on household walls. This type of LED frame photos or picture frames are widely commercially available in the market. But they are fixed for certain selected pictures or photos that we may not like. And that too is priced a bit high due to commercial sales. 

Would you like to have similar LED illuminating frames for your pictures of your choice? Then you can easily assemble such LED blinking circuits by yourself at a very low cost. Here is the assembling guide for such an LED flasher circuit, you would love to assemble and use for your choice of photos or pictures. Come on, now let us learn how to assemble it by ourselves. 

Know your circuit

Build this fascinating LED flasher circuit using very few components. The circuit schematic is shown below. 

The circuit is a simple one and it can be operated on a 9V battery if you want portability.  Just go through the circuit and understand how the connections are made. 

Know your design

There are 18 LEDs driven by a very popular IC 4060. IC 4060 is a 16 Pin DIL integrated circuit used in this circuit. 

It is a binary counter and oscillator IC. With a few external components, it is used as a frequency divider with long time delays. Its operating voltage varies from 3 to 15V. In this circuit, it is powered by a 9V DC supply. 
Pin 16 is connected to the positive power supply and pin 8 is grounded to get a negative power supply. The clock pulse outputs are taken from pins 4, 5, and 6. 
The RC components connected to pins 9, 10 and 11 generate the required outputs. The frequency can be controlled through a variable resistor connected to pin 10. 

Pin 4 is connected to the bus of D1, D4, D7, D10, D13 and D16 

Pin 5 is connected to the bus of D2, D5, D8, D11, D14 and D17.

Pin 6 is connected to the bus of D3, D6, D9, D12, D15 and D18. 

Pin 4 delivers a medium flash rate, while pin 5 is fast and pin 6 has a slow flash rate. The sequential combination gives a fascinating flash of LEDs. 

One should assemble and connect the power supply to enjoy the flashing effect. 

Know your assembling

The circuit can be assembled on any general-purpose printed board. The LEDs can be arranged into a photo frame shape to enjoy the flashing effect. Generally, RED colour LEDs can be used. If one wants, one can try with other coloured LEDs. However, the current consumption will be larger depending on the colour of the LEDs. 

Please use a 16-pin DIL IC socket for the CMOS IC 4060. A 9V power supply can be connected to the circuit using a simple on/off switch.
