HI,
i'm trying to realise a little project with Arduino and since i'm new in all this field, i want to know if it's faisable to wire all the led tubes and the dc motor with only one Arduino board, and if so, what are the other components needed for this little project (transistors, relays).
Thank you for your help
Attatched to this message a diagram.

Hey Buddy,
Unfortunately you cant, The arduino can only give you 5V and you need 12V.
You need a 12V supply for your loads, than use a 5V voltage regulator for your arduino . You need a transitor to interface the arduino with those loads. The 5v from the arduino will switch on a transistor and a transistor will switch on the motor, if you dont understand something ask me
To add to what bastjan said. You could replace the dimmers with the transistors and use the PWM functions to dim the LED strips. There are 6 PWM capable pins on an Uno. You will need some sort of driver for the motors. You can use a transistor for each motor if they spin in one direction only. An H-bridge will be required if the motors need to spin forward and reverse.
Hi,
Thank you for your quick replies.
may be i was not precise in my first post, but the motors and the led tubes will be linked to a 12 v source, the arduino, will be used to turn the motor in one direction, just for the speed, and on and off, and for the leds to control the light, let's say 25% light, 50%, 75% ...
what i need to not to burn the Arduino.
Thank you
i'll modify my diagram, to clarify it
and thank you again
Thank you bastjan
