In order to operate the LED, the pin will be used as an output. Pin 13 is an I/O pin which means that the chip can input or output signals through it. (Note that the resistor and LED discussed here come soldered on the Arduino Nano module. The other end of the LED is connected to ground. That resistor is connected to an LED light. Arduino Pin 13 is connected to a resistor (the zig zag). For now, let's consider the isolated portion shown in the image. On the Arduino Nano, there is a lot of circuitry and components. Since it is called "13" within an Arduino program, let's also stick with calling it "13" for now.

And finally the Arduino software calls it pin 13. It is controlled by the 5th bit of IO port B inside the chip, so it can be called B5. It is the 17th pin of the chip, so it call be called pin 17. Notice that this pin has a few contradictory "names". It is circled in red on the image of the ATmega328 Microcontroller above. Electrons flow out of this pin after powering the ATmega328 Microcontroller.ĪRDUINO PIN 13 is one of the General Purpose IO (GPIO) pins. On the Arduino Nano, the GND pin (there are actually three) connects to the ground of the USB cable. Electrons flow into this pin to power operations of the ATmega328 Microcontroller. On the Arduino Nano, the VCC pin (there are actually two) is suppled with 5Volts DC power from the USB cable. Of the 32 pins on the ATmega328, let's make note of these three:

The ATmega328 Microcontroller features a modified Harvard architecture 8-bit RISC processor core, 32 KB ISP flash memory with read-while-write capabilities, 1 KB EEPROM, 2 KB SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible timer/counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented 2-wire serial interface, SPI serial port, and an 8-channel 10-bit A/D converter. The square package of the chip is called a 32-pin thin quad flat pack (TQFP-32). That chip is an ATmega328 single-chip microcontroller. Looking closely at the Arduino Nano, notice the square black chip just behind the USB-C connector. Take each step slowly, mind the details, and don't be afraid to ask for help. When you persist and enjoy the adventure, a great deal of satisfaction can be derived from this hobby. Building and experimenting with electronics, while very rewarding, can be tricky, challenging, and even frustrating at times. Most importantly, you will need a sense of adventure, hacker spirit, patience, and curiosity. Have a look at the HackerBox Deluxe Starter Workshop for a set of basic tools and a wide array of introductory activities and experiments. A computer for running software tools is also required. If you would like to automatically receive a HackerBox like this right in your mailbox each month with a $15 discount, you can subscribe at and join the revolution!Ī soldering iron, solder, and basic soldering tools are generally needed to work on the monthly HackerBox.
