You're in the right place!\u003c\/p\u003e\n\u003cp style=\"line-height: 20.7999992370605px;\"\u003eThe Arduino UNO is very flexible when it comes to power requirements, and is able to \u003cspan style=\"line-height: 1.6;\"\u003eoperate via the DC Barrel Jack on a supply of 7V to 20V. However, i\u003c\/span\u003e\u003cspan style=\"line-height: 1.6;\"\u003ef the board is supplied with less than 7V, the unit’s performance could become unstable, and the 5V I\/O pin may end up supplying less than 5V, which could cause additional circuitry to function incorrectly.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"line-height: 20.7999992370605px;\"\u003e\u003cspan style=\"line-height: 1.6;\"\u003eVice versa, using an over-voltage power supply up to 20V will cause the regulators on the board to run at full-whack, dissipating the extra voltage as heat. This is both inefficient, and could cause over-heating of the Arduino!\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"line-height: 20.7999992370605px;\"\u003eTherefore, the recommended voltage is 9V to 12V. This is a nice middle ground which enables the board regulators to easily dissipate any unrequired energy, and additionally, supply the correct voltage to the various I\/O pins on the Arduino.\u003c\/p\u003e\n\u003cp style=\"line-height: 20.7999992370605px;\"\u003e\u003cspan style=\"line-height: 20.7999992370605px;\"\u003e\u003cstrong\u003eNote: The Vin pin on the Power Pins I\/O will copy the voltage input supplied through the power jack, and act as an output of that voltage.
