Playing with Grove – LCD Displays

Recently I have come around to really enjoy the Grove sensors and displays from Seeed. They are so convenient!

Grove uses a 4-pin cable to make attaching and removing the addons crazy simple. You can’t even plug them in the wrong way!

You don’t have to worry about voltages, and they each have Arduino libraries. Unfortunately, right now I have found the ESP8266 support spotty. Will keep working with it.

Now, you don’t HAVE to use Arduino. I also have a Raspberry Pi board to try out.

Grove I2C LCD Displays

Today I wanted to share the two LCD displays that I have been testing.

The one pictured above is a straight graphical display. It comes with a nifty tool allowing you to convert a bitmap into C code. Of course, I had to convert my logo 🙂

If you only have a line or two of text, this RGB backlit display is lovely.
