Linkedinhi everyone,
I've made this project given below in the picture attached, when i give 12v supply, the temperature of 555 ic increases. when i put a resistor greater then 100 ohms for current drop at the output of 555 ic ,then the voltage is not able to operate RELAY of 12v. and when i put 100 ohms resistor everything goes well except that temperature rise in 555 timer ic and BJT aswel. if someone could help me in this case, I'd be very thankful
