How connect LCD I2C to Arduino?
It is much easier to connect an I2C LCD than to connect a standard LCD. You only need to connect 4 pins instead of 12. Start by connecting VIN pin to the 5V output on the Arduino and connect GND to ground….Hooking up an Arduino Uno to an I2C LCD display.
| SCL | SDA | |
|---|---|---|
| Arduino Nano | A5 | A4 |
| Arduino Mega | 21 | 20 |
| Leonardo/Micro | 3 | 2 |
What is LCD I2C module?
I2C_LCD is an easy-to-use display module, It can make display easier. Using it can reduce the difficulty of make, so that makers can focus on the core of the work. We developed the Arduino library for I2C_LCD, user just need a few lines of the code can achieve complex graphics and text display features.
How do I set up I2C?
The I2C Software Protocol
- Send a start sequence.
- Send the I2C address of the slave with the R/W bit low (even address)
- Send the internal register number you want to write to.
- Send the data byte.
- [ Optionally, send any further data bytes]
- Send the stop sequence.
How do I connect my I2C device?
When you connect two devices to each other using the I2C bus, you just need to connect the VCC pin from one device to the VCC pin from the other device, and do the same to the SDA, SCL and GND pins. Well, just look at the pretty picture! One of the devices will assume the role of the Master.
