The board can be powered by an adapter that ranges between 5-20 volts but the manufacturer recommends keeping it between 7-12 volts. The barrel jack is usually connected to an adapter. ![]() There are three ways to power the Arduino Mega Board:īarrel Jack – The Barrel jack, or 7-12V DC Power Jack can be used to power our Arduino board. Are you a beginner? Can't decide which book to read? Check out this article on Best Arduino Books for beginners How to power the Arduino Mega 2560? RESET Button-It is used to Reset the board, recommended to press it each time we flash some code to the board. It provides the basic timing and control to the board. ![]() This allows it to effectively find a balance between power consumption and processing speed.Ĭrystal Oscillator- The Crystal oscillator has a frequency of 16MHz, which provides the clock signal to the microcontroller. ![]() Even if there are any changes in the input voltage of the regulator, the output voltage is constant and steady.ĪTmega2560P : It is an 8-bit AVR RISC (Reduced Instruction Set Computer) based microcontroller that executes powerful instructions in a single clock cycle. The primary use of a voltage regulator is to control the voltage level in the Arduino board. Voltage Regulator-The voltage regulator converts the input voltage to 5V.
