what transistor for 5v dc motor switch

What transistor would you recommend to use as a 5v switch for driving 5v dc water pump?
Is below drawing ok?

Not possible to recommend a transistor without knowing the stall current of the motor.

Nor choose a step-up converter... Which pump exactly?

If you can run your motor direct on 3.7V that will be so much better (the step up converter
can be smaller cheaper because it doesn't have to handle motor current). However the pump
will run slower.

In general its bad to share motor supply with digital electronics too, so removing the motor from
the Arduno 5V rail is good.

What ever the transistor you need a resistor in its base.
Please google
Transistor symbol
And use the one everyone understands instead of making it up.

Look, seems to me you are people who are having a blast, not nice.

@groundfungus everything is possible, even for you to give strait answer possibility is greater than zero
the normal person would take normal values and give answer withing error margin, which in case of 5V motor would be 0.01A, 0.1A, 1A not 10A, and not 100A, of which you seem not normal but between 10-100A interval.

@MarkT When you say something is not good then it would be really cultural to say what is not good exactly Why. You replied in my other topic and there was this pump, the same one.

@Grumpy_Mike You take the time to answer and say ‘‘google it’’. Well Mike I think you should google and see that when you google you get only paid arduino advertisement, and the only thing to do is to ask you here on this forum what transistor to use. I do have one more question for you Mike: What is the problem in understanding my drawing, you do understand that these are symboles and can be anything if you do understand what they represent.


The pump is normal DC motor pump 5V 0.2A found on ebay for 1 usd.
There cannot be two batteries in my application.

With that attitude, good luck getting help here. Groundfungus drops the mike.

@groundfungus It is your attitude that is ill mannered, also I take your mike and sell it on ebay for 3 cents unsuccessfully every time. That means you never had an intention of giving strait answer in the first place.

Total crap. Do not tell lies. I just did it. See the attached screen dump.

I do have one more question for you Mike: What is the problem in understanding my drawing, you do understand that these are symboles and can be anything if you do understand what they represent.

Because the base emitter and collector are not identified in your made up symbol.

Your problem is this:-

Grumpy_Mike:
Because the base emitter and collector are not identified in your made up symbol.

Dude I asked what transistor to use, emitter and collector should be obvious from the picture in the first place. I cannot understand how would the answer be different if I used standard symbols or words written below custom symbols.

I can understand that you are counting posts but for the online community would be great to give strait answers, cause now what you have done to someone who is also searching for same answer that they will have to make new thread.

Dude, you were asked some basic questions about your motor. Dude, if you want help answer the questions.

...that they will have to make new thread...

Do not. That is not a suggestion. It is a statement. It is not open for discussion.

Buddy I gave answer 2 times allready in #4 replay in this very thread. And I quote:

which in case of 5V motor would be 0.01A, 0.1A, 1A

That means:

I wanted answer in the opening post, what transistor to use for motor with normal current in 0.01-1A interval. That are at least 3 transistors: one at 0.01A, one at 0.1A and one at 1A. Of which the one at 0,01A I would not suggest based on power.

So what I asked was what transistor would you use for 0.1A and 1A 5V DC motor. That should be clear from my question to everyone.

The pump is normal DC motor pump 5V 0.2A found on ebay for 1 usd.

Which means that if you cannot read this thread cause of spam messagess someone who is also looking for an answer cannot even less.



-------------->>>>>>>>> DC MOTOR IS 5V 0.2A

A snippet taken out of context altering the meaning does not qualify as a quote.

If what you wrote was clear we would not be on reply #11. It would certainly help if you refrained from including pointless bullshit like the meme.

So what I asked was what transistor would you use for 0.1A...

2N2222.

...and 1A 5V DC motor.

Just about anything starting with "IRL" from my International Rectifier sample kit.

Thank you very much for answer.
