What is the maximum input voltage recommended for an Arduino pin?
Tech specs
| Microcontroller | ATmega328P |
|---|---|
| Operating Voltage | 5V |
| Input Voltage (recommended) | 7-12V |
| Input Voltage (limit) | 6-20V |
| Digital I/O Pins | 14 (of which 6 provide PWM output) |
How much current can an Arduino pin handle?
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 max voltage that an Arduino can read?
5V
The Arduino Uno can read voltages on one of six analog input pins. The maximum input voltage is 5V, and the analog input readings are returned as 10-bit integer values. The maximum numerical value for a (unsigned) 10-bit number is 1023.
How much voltage do Arduino pins output?
If the pin has been configured as an OUTPUT with pinMode(), its voltage will be set to the corresponding value: 5V (or 3.3V on 3.3V boards) for HIGH, 0V (ground) for LOW. If the pin is configured as an INPUT, digitalWrite() will enable (HIGH) or disable (LOW) the internal pullup on the input pin.
How many analog pins are in Arduino Uno?

What is the maximum voltage can be supply by each of the digital pin of Arduino Uno r3?
Each of the 14 digital pins on the Uno can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms.
How much current can Arduino 5V pin supply?
5V pin has a maximum draw of 0.8A. It should be noted that the 3.3V and 5V circuits are combined, so 0.8A is also the combined maximum current draw of both these pins. It should also be noted that 0.8A is the theoretical maximum determined by the on board voltage regulators.
Which Arduino has the most pins?
The board with the most pins is the Mega 2560, which comes in with a whopping 54 Digital I/O pins (were 15 of them have PWM) and has 16 Input Analog pins. Surprisingly, the Micro has the 2nd most pins out of the three, having 20 Digital I/O pins (with 7 of them having PWM) and 12 Input Analog pins.
How many analog pins Arduino Mega?
16

| DC Current per I/O Pin | 20 mA |
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.
What is the maximum voltage that an Arduino can output?
Voltage limits on input/output pins: -0.5 – +5.5V max. If you need to read in a voltage on an Arduino digital or analog input pin, ensure it is between 0 and 5V. If it is outside these limits, you can bring down the voltage using a voltage divider.
How does the Arduino Uno measure voltage?
Reads the value from the specified analog pin. 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. On an Arduino UNO, for example, this yields a resolution between readings of: 5 volts / 1024
What is the maximum input voltage for the I/O pins?
The Uno website says: – Input Voltage (recommended): 7-12V – DC Current per I/O Pin: 40 mA Is this correct? 7-12V is the maximum input voltage you can apply to the external DC input power jack. The analog input pin voltage is limited to 0V-5V.
What are the Arduino pin numbers corresponding to the analog pins?
The Arduino pin numbers corresponding to the analog pins are 14 through 19. Note that these are Arduino pin numbers, and do not correspond to the physical pin numbers on the Atmega168 chip.
