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?

8 volt need from arduino uno

How were you connecting the 5V to UNO.
