Hello, how are you?
In my previous post, I have discussed on the pin
configuration of NE555 timer ic,
Today I am going to apply the astable configuration of
555 ic to blink a led with a defined interval of time,
The astable mode of 555 is a free running oscillator
condition, which generates pulses with defined time interval,
We get the pulse output from pin no 3
In this led blinking project, we will use the output
pulse to glow the led, NE555 can deliver enough power to drive the led.
Required component list-
1.
One NE555 timer ic
2.
Resistances- 1k, 10k,220ohm
3.
Electrolytic capacitor -10 micro
farad
4.
Ceramic capacitor-0.01 micro farad
5.
One led
6.
One 6 volt or 9 volt power supply
source
Circuit diagram-
Note-
you can change the time delay of blinking by changing the values of capacitor and resistance,
You
can use 220 ohm resistance with the led instead of 1k,
Actually
I have discuss a simple application of
astable mode, this mode is often used in electronics to generate continuous
pulse, which is used in triggering other digital circuits,
You
may generate tones using the pulses, just put a speaker in the place of the
LED,
