Is Arduino a 3.3 or 5
All official Arduinos run on 5 volts, which for a long time was the 'standard' voltage for hobbyist electronics and microcontrollers. But now the coolest new sensors, displays and chips are 3.3V and are not 5V compatible. For example, XBee radios, and SD cards and acellerometers all run on 3.3V logic and power.
Is Arduino Nano 3.3 V or 5V
The nano Iot uses a Arm® Cortex®-M0 32-bit SAMD21 processor, this is a 3V3 only processor, never connect anything that produces a voltage greater than 3V3 to that device. This normally means using 3V3 to power your sensors. To allow you to power it from a regulated 5V supply, using the onboard regulator.
Can Arduino Uno run on 3.3 V
It can be a wall adapter that gives out constant 5V or a DC-DC converter that is connected to a battery or a set of batteries. You can use both the 5V pin and the 3.3V pin to provide power to modules that are connected to the Arduino. But you can't use the 3.3V pin to power your Arduino Uno/Nano.
Will Arduino read 3.3 V as high
The Arduino UNO uses the Atmega338p micro controller. A digital input will be read as a logic 1 if the voltage is in the higher than 0.6 x Vcc. So even if Vcc is 5V and you have 3.3V as the digital input high state, it will still read it as logic 1 since it exceeds the threshold of 0.6x5V = 3V.
Can Arduino take 5V
The most common and easiest way we can power an Arduino board is by using its onboard USB connector. The USB connector provides a regulated 5V line to power the board's electronics. However, 5V from the USB connector can also power external components through the 5V pin that can be found in Arduino boards.
Will 5V work with 3.3 V
A 3.3 V device can interface with a 5V device without any additional components. For example, a logic 1 (HIGH) from a 3.3 V device will be at least 2.4 V. This will still be interpreted as a logic 1 (HIGH) to a 5V system because it is above the VIH of 2 V.

Can I use both 3.3 V and 5V Arduino
Yes, you can power something from the 5V pin and something else from the 3.3V pin.

Can Arduino work on 3.7 V
3.7V LiPo batteries are useful for low-power Arduino IoT applications. The 600mAh battery shown here can power a standard Arduino Uno board for a few days under moderate processing conditions, and up to several months with the right sleep routines and modifications (power down, no LED, etc.)!
Is 5V enough for Arduino Uno
Like already mentioned, you need a minimum of 5V to power up an Arduino. There are two ways you can do that. Use a 9V battery and connect it to the DC barrel jack.
Is Arduino 5V or 12V
The regular Arduino "works" at 5V (some versions run at 3.3V). The board can accept 12V into the barrel jack and it goes-through a 5V regulator. The inputs & outputs are 5V (~5V is high or logic-1, and ~0V is low or logic-0). You can't feed 12V from a sensor directly into an input.
Does USB use 5V or 3.3 V
The USB port can supply the only 5V. So if you use the USB port as a power supply, the jumper cap of the output port MUST be at 5V; or else, there will be no power supply. The DC input port uses a 5.5mm/2.1mm plug, with a voltage ranging from 6.5V~12V. With a DC input, the output ports could switch between 3.3V and 5V.

Can you use 5V for 3.3 V
The easiest way to convert a 5V analog signal to a 3.3V analog signal is to use a resistor divider with an R1:R2 ratio of 1.7:3.3.

Can Arduino work on 5V
Arduino boards can operate satisfactorily on power that is available from the USB port. It provides 5V DC voltage and can be sourced from the port from a PC, wall socket adapter or portable power bank.

Can I power Arduino with 5V 2A
This AC to DC power supply will do 5V at 2A! They're switch mode power supplies which means the output is regulated to 5V. These have a standard USB 'A' connector for the output so you can power your Arduino, Raspberry Pi, etc.
How to get 3.3 V from 5V Arduino
Method #1 – Voltage Divider
A voltage divider is a simple circuit which reduces a large voltage into a smaller one. Solving the formula above with Vin=5V, R1=1000ohms and Vout=3.3V.
Is Arduino due 5V tolerant
Warning: Unlike other Arduino boards, the Arduino Due board runs at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Providing higher voltages, like 5V to an I/O pin could damage the board.
Can Arduino read 5V
Arduino boards contain a multichannel, 10-bit analog to digital converter. This means that it will map input voltages between 0 and the operating voltage(5V or 3.3V) into integer values between 0 and 1023.
Can Arduino output 5V
5V. This pin outputs a regulated 5V from the regulator on the board. The board can be supplied with power either from the DC power jack (7 – 12V), the USB connector (5V), or the VIN pin of the board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board.
