Other Arduino Boards. Arduino Nano, Arduino Pro Mini, Arduino Mega, Arduino Due, Arduino Leonardo. Overview. Arduino Uno is a microcontroller board based on 8-bit ATmega328P microcontroller. Along with ATmega328P, it consists other components such as crystal oscillator, serial communication, voltage regulator, etc. to support the microcontroller.

Electric Motor Speed Control - PWM vs analog voltage

/1/2015Hello, would it be possible to connect a pwm pin from the arduino to a mosfet gate pin and achieve a variable voltage regulator depending on the pwm # (0-255)? The mosfet will be switching power from two 26650 lithium cells which can discharge 30 amps at a time each to heat up a coil that will be in the . 2 ohm range.
