Introduction: 555 Timer Blink Circuit!
In this instructable i will show you how to make a 555 Timer Blink Circuit!
Step 1: What You Need
What You Need To Build The Circuit-
1x 555 timer ic,
1x 33uf, (or any capacitor the higher uf the lower the blink rate!)
1x 10k Resistor,
1x 1k Resistor,
1x 270 ohm resistor,
1x 9 volt battery clip,
1x 9 volt battery,
3x Breadboard jumper wires,
To make the build easier i have provided the schematic above!
Start by placing the 555 timer on the breadboard. Then place a 33uf capacitor with the positive leg on pin 2 and the negative on pin 1.
Now place a jumper wire connecting pin 2 and 6 together.
Place the 270 ohm resistor from pin 3 to an spare hole on the breadboard.
Now connect the LED's positive leg to the free side of the 270 ohm resistor and the negative leg to GND.
Connect one side of the 1K resistor to pin 7 and the other side to pin 8
Now place a 10K resistor connecting pin 6 and 7 together.
Lastly connect pin 1 to GND and pin 8 To Positive and connect the 9 volt battery.
Step 9: Done
