I ordered a pro mini and has thus far been unsuccessful in programming it. I am using an uno to program it and can successfully send sketches to the uno but not the pro mini. I also found that the way to connect the pro mini to another board to program it is complex enough that it defeats the purpose of going to a smaller board. My requirements are to have a water resistant enclosure that allows access to the arduino to easily reprogram the morse code message and this does not seems practical with the pro mini with how it must be connected even if I got a FTDI and the uno is simple, just plug in the USB.
I have yet to test the headlight Paul__B and I believe to determine whether or not I need a pre-heat circuit is whether the led functions properly or cuts in and out, is this correct? I have heard in some instances that even with a regulator a stator does not produce "clean" enough power for leds.
The motorcycle does not have a battery TomGeorge. It started life as a motocross bike and have upgraded the stator to handle the additional power needs of a headlight and brake light. Companies such as Baja Designs use a similar setup with their dual sport kits which provide everything you need to make a dirt bike street legal.
I orderded a mosfet before you posted 6v6gt, so I am going to try and make the one I ordered work.
How Can I connect the mosfet to the uno and can I remove the pin connectors on the uno to solder the connections? Googling provided answers using breadboards but there must be another way?
One more challenge is how to wire power to the arduino itself, I can run power from the stator after the regulator but how to make the actual connection? Remove the uno power port and solder to that?
