The Arduino Uno R4 WIFI provides one I2C bus on the pin header, which has no pull-ups on the board. Thus, we need to connect a pull up resistor between SDA and VDD and SCL and VDD. In the example two ...

This is a useful addition to my previous article “Arduino EEPROM”. The article is still available ... four 2-way jumper pins (J1-J2-J3-J4), two I 2 C pull-up resistors (R2-R3), and finally a 4-pin ...

Aqui iremos escrever e ler em duas memórias EEPROM (Electrically Erasable Programmable Read-Only Memory) utilizando o barramento I2C (Inter-Integrated Circuit) do Arduino. Copie o código localizado no ...

Before we get started into programming I2C using two Arduinos. We need to learn about the Wire library used in Arduino IDE.. The library <Wire.h> is included in the program to use the following ...

It explains some stuff about EEPROM but nothing about I2C. I still recommand to read the specifications if you want to know how it works. Its a simple interface so the specs are easy to understand.

I am not completely suprised there are some bugs in de Arduino i2c lib in that respect. Writing an reading to/from an serial EEPROM is really no rocket science (compared to e.g. the BMP180 ...

The PCF8582C-2 is a floating gate Electrically Erasable Programmable Read Only Memory (EEPROM) with 2 kbits (256 x 8-bit) non-volatile storage. By using an internal redundant storage code, it is fault ...

Meet the Arduino Compatible RFID Reader Module. It can hold card data for up to five cards, takes seconds to program, and holds card data in EEPROM memory, which means that the cards are saved ...
