What is VCC in Arduino

The VCC (or Vdd) is one of the main power supply pins on an Arduino board. It supplies power to the microcontroller and other components on the board. It is typically connected to a power supply or battery for the board to operate.

VCC in Arduino Uno

In the case of Arduino Uno, the VCC pin is connected to the +5v pin. This allows the board to operate on 5 volts and supply power to all the other components on the board. Additionally, the +5v pin is also connected to the VIN and USB pin, which means that the power can be supplied from either the USB or any external power source.

What is VCC used for?

VCC in Arduino is used mainly to power the microcontroller and other components on the board. It is important to ensure that the right voltage is supplied to the board for it to operate efficiently. As such, it is important to understand the power requirements of your board before connecting it to the power source.

What are some common VCC voltages?

  • Arduino Uno: +5V
  • Arduino Pro Mini: +3.3V or +5V
  • Arduino Nano: +7V to +20V
  • Arduino Mega: +7V to +20V

It is important to note that the required voltage for each board can vary based on the components and the board configuration. As such, it is important for you to consult the datasheet of your board before powering it with VCC.
