Arduino Expand Your Arduino’s Storage with an External EEPROM Part II: Reading from the AT24C256 – A Tutorial in How to Use the I2C Protocol Continued We first began our journey into learning the I2C protocol three weeks ago. In that post, we learned to write to an external EEPROM over the I2C protocol using nothing
Arduino Expand Your Arduino's Storage with an External EEPROM (AT24C256): A Tutorial in How to Use the I2C Protocol In a previous post, we covered how to expand your number of analog inputs by using an external ADC over the SPI bus. Today I want to demonstrate how to
