Hello everyone, In this post, you will find how to READ/WRITE SPI based serial EEPROM chips like winbond W25X10A / W25X20A / W25X40A / W25X80A, Atmel AT25HP256 / AT25HP512, etc. using Arduino Uno. Same can be done with other Arduino boards also.
In many programming languages, in a conditional statement, we use double equal signs (==) together to compare two values. Traditionally, the constant part goes right and the variable part goes left to the double equal signs. The single equal sign is used to assign values to variables.
