ATmega328 Analogue I/O Port Expander Using I2C Bus

This project explains the interfacing of PCF8591 converter (slave) with ATmega328 microcontroller (master) using I2C bus to get direct multiple analogue inputs and outputs. ATmega328 microcontroller (MCU) on the Arduino Uno board consists of only six analogue inputs, which are not enough for some projects that need more analogue inputs. This circuit provides twenty analogue […]
