Using implant with factory keyless open and start

Which transistors did you use and could you please please give me a breif description of why? new to small electronics.

Right so here is what a transistor does, in the image below Q1 Is the transistor:

NPN transistors are used when you have a positive activation I.e. when you drive the pin high (in this case by and arduino) to turn on.


In reply to this… it’s been about a month and I now get what these do, and holy shit… transistors are like the swiss army knife of electronics. I’ve decided I like them.


Fun fact: Modern high end PC CPUs have around 3-4 billion transistors in them.

Graphics cards are even more intense. The RTX 3080 has 28.3 billion…

Fun fact, thermionic valves can be used to perform the same tasks as transistors, but MUCH bigger. :rofl:

Are you the person in my EE101 class that answered the professor’s first-day question saying “electromotive force” instead of “voltage”? :stuck_out_tongue_closed_eyes:

I do have a Physics degree, so if I had been in that class it would have been me.

As for @darthdomo, Scottish is never unintelligible. :laughing:

Wow, since we have derailed already

I have been around a few drunken Scots, and I would disagree with that statement…However in fairness they could still understand each other… So I guess you are correct

Thanks for this turbo2ltr! Finally ordered my xEM and xNT. I would like to set this up but was wondering if you have a step by step? I haven’t really done any wiring or board work previously.
