FLASHING LED

This is a simple LED project for starters and one of the first LED project that I did .It will make the LED flashing at the rate I decide . I had lot of fun doing this one , every time I changed the value of resistor or capacitor , LED keep changing the time between flashing . Let’s build this thing.

Connection :-

1 . Connect pin 2 and pin 6 of 555 IC
2 . Connect pin 4 and Pin 8 of 555 IC
3 . Connect 47mF capacitor +ve ( longer leg ) to pin 2 and -ve to ground.
4 . Connect +ve (longer leg leg ) of LED to pin 3 and -ve to pin 1
5 . Now connect one of the 10k resistor between pin 8 and pin 7
6 . Now connect other 10k resistor between pin 7and pin 6
7. Finish the circuit with battery connection , +ve to pin 8 and -ve to pin 1

If you have problem in identifying the pins of 555 timer IC checkout my post on the 555 timer IC which helps to identify the pins and the function of each pins.

If your connection are correct LED Will be flashing . If you are haveing problem with circuit , leave a comment and I Will help you.

Components Required :-

1. Resistor – 10k x 2
2. Capacitor – 47mF
3. White LED
4. 555 IC
6. Wire
7. 9V battery
