I will show a simple circuit to boost your Arduino 5V to 12V or more.
For this you only need 6 general components, one Arduino GPIO and 4 lines of code.
The circuit can boost 5 Volt to 12Volt and deliver 500mW.
Other voltages are also possible, I will simulate, build and measure the circuit, and show you how to configure it to meet your needs.
