When developing electronic projects, the power supply is one of the most important elements of the entire project, and more often than not, a power supply with multiple output voltages is needed. This is because different sensors and other consumers require different input voltages and currents to operate effectively. In this case, the power supply is very important, which can provide several voltages. There are options where you can use external power supplies such as RPS (Regulated Power Supply) or AC adapters, but then you need more than one and the whole system becomes bulky.

Therefore, we offer you the development of a universal power supply. To do this, we use the Arduino UNO module, which will have several output voltages: 3.3V, 5V and 12V.
