ON Delay Timer Using 555 IC

00:55:40

On delay using 555 .
This circuit holds on for some period before switching on. This is brought about by R1 and C1 for the determined period. For now  am using 10uf for C1. I have voltmeter attached to  it to monitor the rise in voltage as it charges. Once it gets to  ⅔V of line voltage, it will output at Pin 3 . R1 300kΩ can be potentiometer to set desired time period.
20kΩ is for quick capacitor discharge.
