Hello frinends
I've an interesting question (because surprisingly I cannot find the answer on Google):
I've read the voltage values with an multimeter, from 5v and 3.3v arduino pins, and I read in 5v pin = 5.68 volts! And from 3.3v pin = 3.7 volts! Is that normal?
I've simply connect the arduino to an USB cable to the computer, and nothing more attached to the arduino!
And more surprisingly I've read the values from Vin pin, and i've read 5.09 volts!
Is that normal? Please explain to me!
I'm asking this because i need for an project LCD Nokia exactly 3.3v and i'm worried to burn the lcd. Is voltage divider with resistors an option?
Thanks!
