Can i plug a mini motor in and spin it to see how much voltage it has? How would i wire this up? Do i need a resistor in series to limit current? Is the arduino at risk of shorting? Thanks for the help.
have a look at how-to-get-the-best-out-of-this-forum
e.g.
- what Arduino are you planning to use
- give details of the motor (AC/DC, 3-phase, voltage, etc)
probably simplest approach initially is to use a multimeter?
this will give you some idea of the voltage etc etc
i am planning on using an arduino uno. 2phase motor (the small ones) idk what voltage, but spinning it by hand gives me 1.7 volts on my multimeter. is there anyway i can read this using the arduino? I want to measure it using the arduino specifically because i wanna see if i can use it as a mini generator when i 3d print a crank for it.
if you do a web search for Arduino ADC you will get plenty of links, e.g. projects - arduino ADC
