Topic: 8 volt need from arduino uno (Read 9480 times) previous topic - next topic


I made a project in the simulator proteus. In this project, I use Arduino Uno R3, an LCD monitor, a buzzer, a LED. I saw there is a need minimum volt and I use 5 bolt port but then the circuit is not working. So how can I get 8 or 10 volts from Arduino?


How were you connecting the 5V to UNO.

I made a project in the simulator proteus.
Why are  you asking here? Proteus is a commercial product - go ask their help desk.



The vin pin is made to handle 12v.that's the max the Arduino can handle before it fries but it can handle a little more voltage like mane 14v.
