Hi guys...
I am total newbie at electronics and i am trying to make a relay driver circuit using a 555 timer. The requirements were to generate pulses with 50% duty cycle and time period of 1 minute, 2 minutes, 4 minutes and always ON. I am attaching my circuit diagram... will any of you kind souls tell me if i have made a mistake?
Btw the relay is a 12 V 4PDT relay and has a coil resistance of 100 ohms.
