This is easy dual LED Flasher circuit. It uses IC-555 timer IC as the basic astable multivibrator circuit
This circuit you see the look of the cable multivibrator by the IC-555 timer.
Which I don’t tell you in more detail, because I used to suggest in this
now we would like you to see the dual LEDs glow with alternately flash ON and OFF(see video below)
as you rotate a potentiometer-220K
We will use both resistors-470 ohms to controls the brightness of each led.
If you use the 12-volt power supply from a normal battery, you should use as above resistors are 680 ohms to 1K to protects LEDs.
If you first test the circuit on breadboard same me, we don’t need to put C-100uF electrolytic capacitors because we use clearly DC voltage from the battery.
What is more? Play light bulbs, OK?
Table Lamp Circuit using 555
If you want Power Lamp Flasher at give electric tall power.
As a result try out Table Lamp Circuit the this. It uses the integrated circuit NE555 be pillar equipment. Control the rate blinks of Lamp.
Get , for the transistor power make Lamp 12V electric tall power about 20W or use current 1.6A stick bright get.
The Q3 can use replace get many the number such as TIP41 or H1061 or MJ3055 or will use 2N3055.
The detail is other see in the circuit
3V Lamp flasher High Current by LM3909 If you like to use the integrated circuit LM3909 build be Flasher Circuit. But may get into trouble about apply to Lamp at have the requirement Current tall no. I then introduce to see this circuit can apply to power supply 3V and apply to Lamp 3V 1A get. By use transistor help enlarge current tallly […]
Blown Fuse indicator LED Display A Fuse be the equipment protects that use often most. Because of cheapness can use protect electronics expensive circuit. Generally when fuse torn us can know immediately. but in sometimes Fuse torn already we don’t know. such as in electricity automobile system brake system […]
Led display for battery low volt This circuit uses just integrated number circuit LM3909 and capacitors outside. It work by use NiCad battery 1.25V sizes. or The dry cell is small-sized is other. […]
