Hi, I have been designing a very simple circuit for a project which works with 6.5v, it can work with any voltage from 4 to 12v but I'm using 6.5v just because I had a 220v to 6.5v adapter laying around. In the circuit, there is a relay, which works with the circuit main voltage (6.5v now) but I c…

If it's just a relay, which will draw constant current, put a resistor of appropriate value in series with it. The total resistance is (6.5 / 5) * the resistance of the relay. Subtract the resistance of the relay from the result above to get the resistor value.

Err, no.
6.5 / 5 = 1.3
1.3 * 420 = 546
546 - 420 = 126
