|Why Use so May Wires From Your Lcd to Your Microcontroller? Just Use I2C by nerdshed: 3:59pm On Sep 11|

Have you ever incorporated LCD into your projects? If yes i'm sure you know the hassle involved in soldering 6 digital pins wires to your controller. You use up almost all of your GPIO pins.
What if i tell you there's a way to reduce it down to just 2 asides power and ground. I introduce to you I2C which can be used to drive your LCD. I2C uses 2 bi-directional lines, SDA(Serial Data) and SCL(Serial Clock). The blue potentiometer on is used to adjust the backlight. Now you can conveniently add an LCD to your project and still have GPIO pins for other connections. This article will guide you into working with the I2C module. http://blog.nerdshed.com.ng/2017/06/13/use-your-lcd-with-i2c/.

It depends on the kind of arduino you're using, and the number of pins that the other components will need. Digital pins could also be converted to analog, and vice versa.

Yes but that I2C module helps to reduce the number of wires you use for an LCD from minimum of 6 digital pins to just 2 so you can have more pins for other components to connect.
