Arduino Debugging Checklist

• Make sure you have the correct board selected (Arduino Nano)
• Make sure your code compiles correctly, you can just compile without uploading.
• Check Ports: Tools->Ports, make sure the port selected is a serial port, if it is bluetooth there is an issue there.
• Check Bootloader: Tools->Bootloader, try switching the bootloader from new 32 to old 32 or vice versa.
• Reset the Arduino by holding down the button on it for a few seconds.
• Unplug the Arduino then plug it back in.
• Exit out of the Arduino software and reopen it (make sure to close ALL open software windows).
• Try a different Arduino or Cord.
• Restart your computer.

If your Arduino is still not functioning after trying all of these steps, call an instructor over for help!

Arduino Nano Pinout

Arduino Nano Tech-Specs

• Built-in LED Pin #: 13
• Digital Pins: 14
• Analog Pins: 8
• PWM Pins: 6
• Voltage: 5V
• Input-Voltage: 7-12V
• Current per Pin: 20mA

For more detailed specs, see the Arduino Nano website

Voltage Divider

LED Anode vs Cathode

Basic Circuitry Formulas

Voltage (V in Volts) = Current (I in Amps) * Resistance (R in Ohms)

Power (Watts) = Voltage (Volts) * Current (Amps)

Similarly, Watt-hours = Volts * Amp-hours
