Step 5: 2N3904 NPN BI-POLAR JUNCTION TRANSISTOR, THE FINAL FRONTIER !

The transistor part is nearly done, just the base leg left:
  1. Cut and strip some wire
  2. Twist the wire around the middle leg of the transistor
  3. Solder the wire in place
  4. Solder the other end of the wire to a 10k resistor
  5. Connect this resistor to pin 13 of the arduino with solder if using the nano.
There is no problem providing 5v instead of 3 to the remote? Looks great, I'm planning something similar and will mount it all on the hotshoe with the ir led facing down
<p>In hindsight this would have made more sense as the coin cell is 3v and most arduinos have a 3.3v regulated pin. </p>
<p>Is this the remote you used?</p><p>YN ML-L3 InfraRed Remote Controller for Nikon Digital Cameras</p><p>It would be a lot easier to get the exact same one.</p><p>Thanks for this great instructable,</p><p>Shane</p>
Very nicely done! Thanks.
Thank you. I have now salvaged the arduino from this project so it is now more :( but just wait till you see what I have done with it.
You should add some result pictures.
I am waiting for the solid grey cloud over england to do something more interesting than just sit there, but I will do.
