A simple project is implanted here where the number of IO Pins of an Arduino UNO Board are increased by interfacing PCF8574 with Arduino. Using this IO expander module, you can connect a number of IO devices like Temperature Sensor, Humidity Sensor, 16×2 LCD Display, Status LEDs, Relays, Motors etc. without worrying about the number of IO Pins.

IO Expanders are connected to the CPU by Ribbon Cable on one side, and to redstone input and output by Bundled Cable. One side will only connect to Ribbon Cable, and the opposite only to Bundled Cable; the Ribbon Cable side is facing the player when the IO Expander is placed. On the Ribbon Cable side, there is a monochromatic red display; active output bits (but not input.

I think he’s taking “io expanders” which are considerably more expensive, but offer you more control over the pins - basically giving you gpio registers accessible over i2c or spi, which control the pins kinda like the gpio registers on a microcontroller.

The PI4IOE5V9570 4-bit I/O expander shown in Figure 6 can also drive LEDs directly. It’s a faster device capable of 1MHz I²C operation, but each of its four latched outputs can source 25mA. In this case, the SoC controls the GPIO signals using the I²C interface (through the bridging function in the expander).The SoC issues I²>C commands to the expander, which in turn converts the. I/O Expanders. Xpander devices are general-purpose input/output port expanders to interface digital ASICs via a two-line bidirectional bus (I²C).

Here I am using an MCP23017 IO Expander chip with a Teensy LC. The only other components needed are two 4.7KOhm resistors to pull up the signals on the I2C bus. I'll document this properly another time, but you can see from the picture above I'm only using a small number of pins on the Teensy, leaving most of them free for other things..

IO Expanders. Our general purpose IO Expander (GPIO) products are available with I2C bus interface and 2 to 48 IOs. Some of the products feature an additional INT (INTerrupt) output and/or a REST or OE (Output Enable) input signals. The output is used to signal the microcontroller when any of the inputs state has been changed (from 1 to 0 or 0.
The ESP8266 has only one analog input, so we decided to add an ADC on the I2C bus of the ESP. We start to search for a breakout board with such component. We have found some reference as Adafruit ADS1115 or some with an MCP4725, for example. I often use Arduino Nano on my project and I thought it might be interesting to use a Nano V3 as an I2C.

So only one signal can have a value written on it or read from, and pullup resistors and interrupts are non-existent. However the CD4067 can be used with signals other than digital - as such they are good at being a multiplexer to the analog inputs, something an IO expander can never do. You could, though, use an I2C ADC chip for that. Software. We've put together a Python library to use with your IO Expander, together with some handy examples that show you how to interact with different kinds of devices. You can also use this breakout with Raspberry Pi Pico and other RP2040 boards, using C++ or Pirate brand MicroPython. Additionally, there's an Arduino port of our library.
