Using this IC, you can use only the SDA and SCL pins of your Arduino board to control up to 8 digital I/O ports. A0,A1,A2 are address pin PCF8574 i2c Digital IO Expander Rotary Encoder A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to analog or digital output signals

The PCF8574 device provides general-purpose remote I/O expansion for most microcontroller families by way of the I 2 C interface [serial clock (SCL), serial data (SDA)]. The device features an 8-bit quasi-bidirectional I/O port (P0-P7), including latched outputs with high-current drive capability for directly driving LEDs In February 2018, I ran my sketch (arduino IDE) in my project - ESP32 digital voltmeter and it worked fine - Arduino IDE 1.8.5 and ESP32 Board version 1.0.0. The communication of the digital voltmeter is made with PCF8574 I2C interface. Pullups resistors are 3K3 ohms (VCC = 3.3V We will use the PCF8574 that provides 8 more pins that can be used as input or output. This way it becomes possible to control an 8 channel relay board. Each individual pin can be used as either input or output. It can also be helpful in improving system stability when using ESPEasy for actuators Der PCF8574 kann in einem Bereich von 2,5 bis 6 Volt betrieben werden. Ein Datenblatt gibt es z.B. hier. Eine Besonderheit des PCF8574 ist, dass die Pins im HIGH Zustand nur einige hundert Mikroampere Strom liefern. Will man z.B. LEDs steuern, so muss man die Pins als Eingang (LOW) verwenden PCF8574 GPIO Extender run on the I2C bus, extending the 'IO Pins' which can be controlled by a single host I2C bus. The Address range of PCF8574 is from 0x20 to 0x27 (7 bit address mode). at the max 8 of these devices can be connected in a project to the I2C bus
