Delayed Start Circuit using 555 IC

This circuit does not turn on for XX seconds after power is applied. Adjustable from 1 second to 2 minutes.The delay can be adjusted by changing the resistance between pin 6 and ground.
Either you can use a 1M Variable Resistor or use different resistances to get different delays in turning on the circuit. Just Connect a LED to pin 3 of 555 along with a resistor to delay the start of LED.

Resistances Between pin 6 and Ground and their Respective Delays :

1K-     1s
100k-  10s
220k-  25s
250k-  27s
500k-  56s
1M-   2min

COMPONENTS USED :

1.one 555 IC.

2.one 100uF Electrolytic Capacitor.

3.one 1M Variable resistor or different Resistances (1K,100K,250K etc)

4.one LED.

5.one 470ohm/220ohm resistance.

6.one 9-12V Power Supply.
