hi im a newbie and came across your forum searching for some help
i like setting myself small projects to stop me getting bored but need some help
basicaly what i need to do is use a 1-3vdc varying trigger to make a relay coil powered but i need the relay coil to be isolated from the trigger so was thinking of using a transistor the 1-3vdc would connect to the base and then use the collector or emitor not sure which to feed the relay coil
could someone please help me with a circuit diagram please with resistor values
the relay coil is 12vdc and the resistance is 1k ohm and the only main supply i have access to is 12vdc
thanks in advance if you need any more details let me know please
