In thisArduino I2C tutorialwe will useI2C communication between two arduino boardsand send (0 to 127) values to each other by using potentiometer. Values will be displayed on the16x2 LCDconnected to each of the Arduino. Here one Arduino will act as Master and another one will act as Slave...
In this tutorial, we learn about theSPI protocol and how to use it in Arduino. We will useSPI Protocol for communication between two Arduinos. Here one Arduino will act as Master and another one will act as Slave, two LEDs and push buttons will be connected to both the Arduino. To dem...
In this tutorial, we will learn how to perform RS485 serial communication between two Arduino boards using 5V MAX485 TTL to RS485 module.RS485communication is used in industrial Modbus to communicate with various devices. We will follow the RS485 serial communication protocol and demonstrate it wi...

Step 73: Component Selection - Arduino The Arduino is used to interface the computer with serial communication and to also control the OLED display. An Arduino Nano is preferred, although a Nano Every might work too. Step 74: Component Selection - ATTiny The ATTiny85 is used to control the ...
Have you tried to scan the I2C devices on the bus? This will help you to see if the devices are connected correctly. If you are using the Arduino IDE, you can try this one:WireScan. There are some LCD1602 libs, but the most used is this one:LiquidCrystal_I2C. ...
