| Apr 4, 2021 at 19:52 | comment | added | Mats Karlsson | I wouldn't recommend to share power-supply as disturbance from the high power load could cause erratic Arduino behavior. A simple decoupling capacitor could be enough, en.wikipedia.org/wiki/Decoupling_capacitor or a more complex solution such as buck converter and so on... | |

| Apr 4, 2021 at 19:03 | comment | added | krystof18 | That's why I'm asking if and how to split power from that 12V power supply. | |
| Apr 4, 2021 at 19:01 | comment | added | jsotola | you don't want to use the arduino to supply current to drive peripherals anyway ... LEDs and motors should be supplied externally ... arduino should only provide control signals ... if you are still worried, then use a buck converter to supply 5 V to the arduino | |
| Apr 4, 2021 at 18:54 | comment | added | krystof18 | forum.arduino.cc/index.php?topic=618723.0 - In this forum, they don't recommend that, because if a large current is drawn, it will overheat the built-in power regulator. | |
| Apr 4, 2021 at 18:51 | comment | added | jsotola | so, if it runs on a 12 V supply, then connect it to a 12 V supply | |
| Apr 4, 2021 at 18:42 | comment | added | krystof18 | 6-12V, but it runs on USB too, so 5V minimum i quess | |
| Apr 4, 2021 at 18:37 | comment | added | jsotola | what is the arduino mega power supply voltage requirement? | |
