Hi,
I have a 12 volt 3 watt lamp that I would like to turn on and off with a 5 volt reciever module (as the controller) , so.... I've tried an npn and fried 0ne of two reciever modules that I have, (lol).
Also a 6 volt relay would not operate via the 'module' though it works fine with a separate source..
Question is, (since I have lots of 555's) , can I use one as a two source voltage simple on off switch ?
If so , could you tell me which pins to use (1-8 of the 555) to allow this to work.
I do have a solid state relay on the way to being delivered which I think might work , but would also like to do this with a 555 if possible.
Thanks, for any help.
