Hello Everyone,
I am using 24V relay with avr microcontroller. Everything works fine except the relay. The ULN2003 shows correct voltages when switching is done. The circuit works only where there is a pullup resistor on the output, the switching between 0-24 is also correct. Only issue is when I connect a relay it doesn't work. I have checked the relay, it is just fine. When the relay is connected to ULN2003, it doesn't work.
Why is it happening.
