Character LCDs are a fantastic and cost-effective option when your project calls for a user-friendly output method. Besides being cheap and easy to use, these displays often offer enough usable screen real-estate for displaying simple status messages and interactive menu screens. However, the standard 16-pin interface can be quite a hassle to work with, and all the wires quickly clutter up your previously simple Arduino project. While there are some I2C character LCDs out in the wild, these models are often more expensive and sometimes difficult to work with. Therefore, I decided to build a simple-to-use alternative that allows you to control pretty much any standard 14 and 16-pin LCD display with only four wires.

More than often enough parts of projects will have to communicate with each other or external devices. This can either be done by directly connecting the devices with cables but sometimes it’s more convenient to wirelessly connect the different pieces of hardware. This article will show you how to use the ESP8266 and it also includes two examples for using it with a Raspberry Pi and Arduino boards.
