When ATmega328 chip is used in place of Arduino Uno, or vice versa, the image below shows the pin mapping between the two. Arduino Uno is programmed using Arduino programming language based on Wiring. To

Maximum current from the 5V pin? - Arduino Forum
The Arduino can safely supply 500mA off the 5V pin when connected to USB. Well not technically 500mA, 500mA less the current the Arduino itself is using which I doubt it more than a few dozen mA. When connected to an external source, the onboard regular can supply 800mA, again less what the Arduino itself uses.
How To Use Arduino’s Analog and Digital Input/Output (I/O)
How do I power my Arduino? A more complicated beast than the Raspberry Pi! Unlike the Pi, which states exact power requirements, the Arduino is much more flexible, and can be powered via a number of ports. If you decide to power a circuit via the Power I/O pins, the 3. 3V pin has a maximum current output of 150mA (recommended at 50mA).
Arduino Wattmeter: Measure Voltage, Current and Power
Measuring DC Voltage using Arduino. Created on: 23 May 2013 The point on the resistor divider network connected to the the Arduino analog pin is equivalent to the input voltage divided by 11, so 55V 11 = 5V. In other words, when measuring 55V, the Arduino analog pin will be at its maximum voltage of 5V. // current sample number float
Arduino I/O Functions - Current Affairs 2018, Apache
This is important because it limits the current that can flow from the Arduino through the transistor. This particular resistor limits the current to around 9mA, which is pretty safe to get out of an Arduino I/O pin. The calculation is the following: You have 5V from the Arduino pin.
Acs712 current sensor interfacing with Arduino ac dc
The Uno board and version 1. 0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. The Uno board is the first in a series of USB Arduino boards, and the reference model for the Arduino platform; for an extensive list of current, past or outdated boards see the Arduino index of boards.
