What is the maximum output voltage of Arduino?
Maximum output voltage you can get through Arduino is 5V for Arduino UNO. Maximum current that can be drawn is 40mA from I/O pins and 200mA from 5V Pin.
How much current can Arduino pin supply?
There are 16 digital pins on the Arduino board. They can be used as inputs or outputs. They operate at 5V and have a maximum current draw of 40mA.
What is the maximum output current per pin of an Arduino Uno?
The 14 digital input/output pins can be used as input or output pins by using pinMode(), digitalRead() and digitalWrite() functions in arduino programming. Each pin operate at 5V and can provide or receive a maximum of 40mA current, and has an internal pull-up resistor of 20-50 KOhms which are disconnected by default.
What is the maximum input voltage of the Arduino Uno?
6-20V

How much maximum current can Arduino Uno sink?
Each pin can provide (source) a current of 3 mA or 15 mA, depending on the pin, or receive (sink) a current of 6 mA or 9 mA, depending on the pin. They also have an internal pull-up resistor (disconnected by default) of 100 KOhm.
How long can a 9V battery power an Arduino?
Even with an “expensive” Lithium 9V battery, an Arduino-based project will only last for 1 or 2 days of continuous use.
Can Arduino run on 12 volts?
It will work fine on 12V. You do not have to split it, just supply 12V to the power connector on the Arduino board, it will take what it needs. The only problems you may have are if the motor takes such a big current that the voltage drops too low to supply the Arduino.
