Components in the Japanino and Their Functions
There are quite a few characters and symbols imprinted on the Japanino, but there are
not so many of which you actually need to know the meanings.
Most of the parts you should be familiar with are pins*.
The types of pins are roughly divided into three groups, digital input/output pins,
analog input pins, and power supply pins.
Normally, pins are wired in accordance with the sketch (program).
Analog input pins
There are a total of 8 analog input pins, including A6 and A7 in
addition to A0 to A5 (the A is short for Analog). The input voltage is
read out from 0 to the power supply voltage (5 V, normally) in 1024
steps. You can connect sensors, volume dials, etc. to these pins. In
addition, you can also use these analog input pins as digital input/
output pins by changing the settings in a sketch (program).

Digital input/output pins
There are a total of 14 pins from D0 to D13 (the D stands for Digital). The input pins and output pins for
digital values of HIGH and LOW can be set freely. The 6 pins of D3, D5, D6, D9, D10, and D11 that are
marked with PWM (for Pulse Width Modulation) can be used as pulse width control output pins. Pins
D0 and D1 can be connected to a PC via USB.

Explanations of terms
* Pin: For the Japanino, terminals are referred to in this way. Some terminals may also be called "ports" on other circuit boards. Some terminals may be in the form of sockets. The expression "I/O pin" is also
sometimes used when to represent input/output. "I" stands for "Input" and "O" for "Output."
* GND: This stands for "GROUND," the surface of the earth. Electrically speaking, ground refers to earth ground. The ground terminal is connected to the negative (-) on the power supply.
* PWM: This is the abbreviation for "Pulse Width Modulation." By controlling the ratio between ON and OFF times for a given pulse, you can realize analog output with digital pins.
