I’m wondering how the Arduino can power 1 small 9g servo (the standard blue ones of multiple brands) direct from the pins when the DC Current per I/O Pin puts out a maximum of 20 mA? I believe my servo can spike to 600 mA.
I’m also wondering if it makes a difference to power the Arduino with anything more than 5V because doesn’t the voltage get regulated to 5V anyway? A recent project I have been working on seems to work only at battery voltages higher than 9V when I power through the V-In pin. I thought this might be because more current gets supplied but then I found out that lowering the voltage increases current. Not sure why that is true also because V=IR and looking at that formula it tells me that when you increase either V or I, you should increase the other right?
Confused as fog
