Connecting an LCD with an I2C backpack is pretty self-explanatory. Connect the SDA pin on the Pi to the SDA pin on the LCD, and the SCL pin on the Pi to the SCL pin on the LCD. The ground and Vcc pins will also need to be connected. Most LCDs can operate with 3.3V, but they...
Multiple I2C devices on Arduino: To connect multiple I2C, we have to address each slave device on the I2C bus. I assume you are using the Arduino as master and the other devices as slave. In that case each slave device will have an unique I2C address using which we...
Arduino Uno LCD Screen (2x16, I2C) Male-to-Female Dupont Wires USB Type-A to Type-B cable You can probably get away without buying the Dupont wires as long as you have some other simple wire sitting around and a way to strip the plastic casing on each end. I just listed these since...
Arduino makes creating electronic projects Easy. All you have to do is figure out what you want to make, and then program it! On this site you can find out about microcontrollers: What they are, What's inside them, Why you need them, ...
Hi there, recently I bought an Orange Pi Zero3 with 1GB RAM. I want to connect a 20*4 character LCD display(https://www.tinytronics.nl/en/displays/lcd/lcd-display-20*4-characters-with-white-text-and-blue-backlight-with-i2c-backpack) to it. I have previou
How to Connect a Serial LCD to an Arduino UNO: In this instructable I will show you how I connected a serial LCD 16X2 to an Arduino UNO. There are lots of instructables and tutorials showing you how to connect a regular LCD to an Arduino but not many sho
I2C LCD interfacing with ESP32 SPI Pins By default, ESP32 has two SPI communication channels VSPI and HSPI and the following table provides the default SPI pins for both channels. But if we can also map these pins to other GPIO pins also in Arduino or esp-idf. ...
Once we connect the module we need to program the Arduino Board to work with the Real Time Clock. However, when it comes to programing a communication between Arduino and an I2C module the code isn’t that small and easy. Luckily, there are already several libraries for the DS3231 RTC wh...
Arduino I2C Code Now let’s make the code that will get the data for the X axis. So we will use the Arduino Wire Library which has to be include in the sketch. Here first we have to define the sensor address and the two internal registers addresses that we previously found. TheWire...
