Good job
*nice work*
kya isko 9v ki jaga 12 pe chala sakte hai kya
Ok ok felicitari
A good brother project! How to connect a potentiometer in this project ? Thank you very much
Good idea.
Simple but usefull....👍
If we want to change delay_duration, which one should replace.... resistor or capasitor?
Cap

Ok. Thanks...👍
@@wibowoims527 Yeah, just use a baseline resistor like 1k or like 10 ohm. Then record the time on a graph then you can calculate the amount of capacitance required for a specific time. That’s how I fixed my air conditioner.
@@teku3985 Clear.....👍
How to increase the timing bro
change cap value and rezistance the higher=more time
Used a 2n3904 and switched it around to work right (is opposite than bc547). Used a 9v source and fucker blew its lid... thought 2n3904 handled bigger loads than bc... but your circuit is not right, i had to run wire from switch to pin connecting npn to relay..
