FAQ:
Q: What is the voltage of Arduino?
A: The Arduino has a narrow operating voltage around 5 Volts (3.3 Volts in some) and is sensitive to variation in this voltage. The Arduino design is based on the assumption that a stable 5 Volt power source will be feeding the chip at the heart of the Arduino.
Q: What is power supply in Arduino?
A: The Power Supply will be an Arduino UNO Power Supply Shield which will output multiple voltage range such as 3.3V, 5V and 12V. The Shield will be a typical Arduino UNO shield with all pins of Arduino UNO can be used along with extra pins for 3.3V, 5V, 12V and GND.
Q: What power supply does Arduino Uno use?
A: An Arduino Uno can be powered by a stable (regulated) 5V DC, which you can either supply via the USB power lines, or via the shield connectors, or an unregulated 6-20 V DC (7-12V recommended), which you can supply via the 2.1 mm centre-positive barrel plug connector.
