Morning! I'm not a transistor expert, but I've been told I need 1 x 2N7000 N-CHANNEL MOSFET to wire my WINSTAR OLED to my Arduino.
I've been googling the components in this kit - none the wiser if any are suitable!
http://hobbycomponents.com/index.php/11 ... c1815.html
If not, I'm about to place an order for over £30 anyway - do you have one or possibly 2 2N7000s kicking around you'd just drop into the envelope for me, save me going "elsewhere" for just this one component?
2N7000 N channel MOSFET compatible in this transistor kit?

Unfortunately we don't have any of those parts. What do you need to use it for, driving the back light?

No problems about not carrying the parts. As for WHY - well, I was just following this:
https://github.com/lukecyca/WinstarOLED/ and he writes:
Anyway, I know this isn't your problem, but if you CAN suggest anything alternative/a workaround, that'd be very helpful!
BTW, I know Saturday delivery isn't guaranteed or promised, but what's the realistic last time to order today (Friday) to ensure it leaves today, assuming items are in stock of course?

I've posted a question over there, but he might not reply for days. I don't know enough about why it's there to know what I could use instead. I mean, yes, I understand what a transistor does, but not in this caseThe original LiquidCrystal library doesn't correctly initialize or reset Winstar OLED devices, so this circuit controls the OLED power via a MOSFET-N. The following sample circuit shows the default pins for the library.
Code: Select all
arduino OLED Vcc ------------------------------ Vcc MOSFET-N (d) -------- GND GND -------- MOSFET-N (s) D9 -------- MOSFET-N (g) .....

Re: 2N7000 N channel MOSFET compatible in this transistor ki
Ok it looks like they are using it so that you can turn off the screen with minimum leakage current. This would only be important if you are using it with a battery application and you need to save every last drop of power? If you don't need to turn the screen off then the transistor shouldn't be necessary.
Edit, scrub this, I just noticed the comment. They are using it as a reset. See my next post as a suggestion.

You would need to put the order through within the next 30 mins via first class post. If you do it is likely that you will receive it by tomorrow but please keep in mind that Royal Mail first class is not guaranteed to be delivered in one day. If you do please email us so that we can expedite your order.BTW, I know Saturday delivery isn't guaranteed or promised, but what's the realistic last time to order today (Friday) to ensure it leaves today, assuming items are in stock of course?

If you do need a transistor A FET would be more ideal but there are transistors in our transistor kit that should work fine such as the S8050. Unfortunately at the moment we don't sell transistors separately.but if you CAN suggest anything alternative/a workaround, that'd be very helpful!
Edit:
You will also need a resistor (about 1K to 10K) between D9 and the transistor.

Thanks for going above and beyond the call of duty, Andrew! Order placed in the nick of time, email sent, fingers crossed!andrew wrote:You would need to put the order through within the next 30 mins via first class post
