• Educational projects and DIY electronics
• Compact embedded systems

The Arduino Nano Every is packed with features that make it suitable for both beginners and advanced users. Below are its key technical details:

The Arduino Nano Every has a total of 30 pins, including digital, analog, power, and communication pins. Below is the pinout description:

The Arduino Nano Every is easy to use and program, making it a great choice for beginners and professionals alike. Below are the steps and best practices for using the board in your projects.

1. Powering the Board:

   • Use the VIN pin to supply 7-21V, or connect a regulated 5V supply to the 5V pin.
   • Alternatively, power the board via the Micro-USB port.

2. Programming the Board:

   • Connect the board to your computer using a Micro-USB cable.
   • Open the Arduino IDE and select Arduino Nano Every under Tools > Board.
   • Select the correct port under Tools > Port.
   • Write or load your sketch and click the Upload button.

3. Connecting Components:

   • Use the digital pins for digital input/output operations.
   • Connect sensors to the analog pins for reading analog signals.
   • Use the PWM pins for controlling devices like motors or LEDs with variable intensity.

• Voltage Levels: Ensure that the input voltage does not exceed the specified range to avoid damaging the board.
• Pin Current Limits: Each I/O pin can source or sink a maximum of 20mA. Exceeding this limit may damage the microcontroller.
• Decoupling Capacitors: Use decoupling capacitors near power pins to reduce noise in sensitive circuits.
• Static Protection: Handle the board with care to avoid electrostatic discharge (ESD) damage.

Below is an example code to blink an LED connected to pin D13:

// This example code blinks an LED connected to pin D13 on the Arduino Nano Every.
// The LED will turn on for 1 second and off for 1 second in a loop.

void setup() {
  pinMode(13, OUTPUT); // Set pin D13 as an output pin
}

void loop() {
  digitalWrite(13, HIGH); // Turn the LED on
  delay(1000);            // Wait for 1 second
  digitalWrite(13, LOW);  // Turn the LED off
  delay(1000);            // Wait for 1 second
}

1. The board is not detected by the computer:

   • Ensure the Micro-USB cable is functional and supports data transfer.
   • Check if the correct port is selected in the Arduino IDE.
   • Install or update the required drivers for the Arduino Nano Every.

2. Sketch upload fails:

   • Verify that the correct board and port are selected in the Arduino IDE.
   • Press the reset button on the board before uploading the sketch.

3. Components connected to the board are not working:

   • Double-check the wiring and connections.
   • Ensure that the components are compatible with the board's voltage and current ratings.

4. The board overheats:

   • Check for short circuits in your circuit.
   • Ensure that the input voltage is within the specified range.

Q: Can I use the Arduino Nano Every with 3.3V sensors?
A: Yes, the board provides a 3.3V output pin for powering 3.3V sensors. However, ensure that the sensor's logic levels are compatible with the board's 5V logic.

Q: How is the Arduino Nano Every different from the Arduino Nano?
A: The Nano Every features the ATmega4809 microcontroller, which offers more memory and better performance compared to the ATmega328P used in the original Nano.

Q: Can I use the Arduino Nano Every for battery-powered projects?
A: Yes, you can power the board using a battery through the VIN pin or a regulated 5V supply. Ensure the battery voltage is within the acceptable range.

Q: Does the Arduino Nano Every support external interrupts?
A: Yes, the board supports external interrupts on pin D2.
