Figure 1: Example two-port network with symbol definitions. Notice the port condition is satisfied: the same current flows into each port as leaves that port.. In electronics, a two-port network (a kind of four-terminal network or quadripole) is an electrical network (i.e. a circuit) or device with two pairs of terminals to connect to external circuits.
The Crumbuino-Mega is a low-cost module comparable to the Arduino-Mega 2560 and can be used as Arduino-Mega 2560 in the Arduino-IDE. The Arduino bootloader is preloaded, hence the module is ready-to-use. The documentation shows the pin mapping of Arduino-naming to module pinout. Cuteduino: Cytron Technologies: ATtiny85 Cuteduino Features:
Arduino IDE support with 16/256/320 MHz presets and port of Arduino library. Also works with standard C/C++, stdio, GDB from the shell. Hardware multiply (4 cycles) and divide (32 cycles).
The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2010. [2] [3] The microcontroller board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. [1]
Usually a two-port network is implied but the concept can be extended to networks with more than two ports. The definition of image impedance for a two-port network is the impedance, Z i 1, seen looking into port 1 when port 2 is terminated with the image impedance, Z i 2, for port 2. In general, the image impedances of ports 1 and 2 will not ...
A sketch is a program written with the Arduino IDE. [72] Sketches are saved on the development computer as text files with the file extension .ino. Arduino Software (IDE) pre-1.0 saved sketches with the extension .pde. A minimal Arduino C/C++ program consists of only two functions: [73]

If no printer port is present at 0x3BC, the second port in the row (0x378) becomes logical parallel port 1 and 0x278 becomes logical parallel port 2 for the BIOS. Sometimes, printer ports are jumpered to share an interrupt despite having their own IO addresses (i.e. only one can be used interrupt-driven at a time).
