hellow.

first thing sorry for my bad english


ok for my question.
i have a new arduino uno without a sensors
i buy starter kit for arduino but i need to wait 50 days
and i want to do somthing with my arduino

my qustion is
can i take a sensors like temperature sensor for example from computer m-board
or car or resiver or anything else
sensors from a old i have a lot of electronic devises and i want to know if i can use them :)
thank u and sorry for my english again

Sure you can. You just need to work out how to wire them up to the Arduino. Usually they have a part number you can google to get a data sheet that will help.

i found nothing on google this reason what i here...
can u please give me example? or image of a sensor from pc?

I am not a mind reader. If you have 'old stuff' you should be telling us what you have.

i have 3 complete computers
i have 8 smartphones with broken screen
i have cd players  + car cd players
keyboards mouses
and more
.....
but i dont know how can i know what a sensor from .... all the small things in m-boards or power suplly or any thing else


i found this sensor but i am not sure if its a temperature sensor

ON IT "STC 945 G938"

STC945 is a transistor/amplifier. I just googled that.

CD players will have motors in them for sure. You may be able to drive these from the Arduino. Lots of stuff online for how that can be done.

Laptops usually have a sensor to tell the laptop when the screen is shut. You may also get power supply components. The screen may be usable, but it will take some work. Most laptops I find useless to a great extent as the components are very densely packed and generally surface mount.

Smartphones are in the same category - densely packed and hard to take apart usable components. Some of the older smatphone may have screen that you can use - google the model and see what other have done.

Mouse has switches. Old style ball mouse will have optical encoders.

Bottom line is that you just need to take them apart and have a look.

Many sensors are simple switches or analogue outputs. Look through the Learning tab and write programs using switches for digital inputs and potentiometers for analogue inputs.

Play around with these to work out how they work then modify your programs when you get other sensors.

Thank u so much :)

One of the most important parts i'm always saving from old electronics stuff....


tiny screws..... you can never have too many of them
