i'm new to arduino, so apologies if i say something completely dumb, but can i read if and how one of those standard yellow motors
is being rotated? like, if i move it manually, can i make the arduino know that without some fancy external parts?
Actually, the motor part is the silvery and black pars on the end. The yellow part is a gear box that makes the output shaft turn much slower than the motor. Please tell us more about your device, like what is the voltage rating to power it and what you want to do with it and where does and Arduino fit into the project.
The motor you have looks to be a 3 ~ 6 VDC gear motor. They are inexpensive little gear motors. If you try to spin the output shaft you may strip the gears.
Can you detect shaft rotation using an Arduino? Maybe. Measure across the terminals with a good voltmeter and see if the motor outputs a voltage at all. Remember you risk stripping the gears depending onthe reduction ratio.
Exactly in detail what is your objective?

its probably a 5v, i want to detect if the motor is spinning in code so i can use it later, and arduino is the only thing i could think of and that i have to do it
idk i just wanted to know if the motor is being rotated at all so i can make it light an led or something, its probably a 5v i dont have a voltmeter i basically just have an arduino and some motors and some other basic things
Before we go any farther in this discussion,can you actually make the motor rotate by turning the output shaft? If this is what you mean by the motor spinning. IF you mean does the motor have enough power connected to make it spin, then that is a different problem.
To detect if the motor is turning from within code or which direction the motor has to have an encoder. A single channel (incremental) encoder can tell that it is running and how fast, but a quadrature encoder is required to sense direction, too.
oh wait there have been some developments and i dont need this anymore. thanks yall
Hope they are not fatal!
