An alternative to serial for talking to the display.

I 2C Communication - I 2C is a two-wire serial interface.

Serial Communication - This is the simplest of the three communication standards used to talk to the display.

How to Solder - To connect to the display, you'll have to solder either wire, headers, or another connector to it.

In order to control the decimals or individual segments, knowledge of binary will be important.

Binary - The data sent to the display comes in 'packets' of bytes.

Consider reading through these tutorials before continuing on: Before You Beginīefore reading about how to hook up the Serial 7-Segment Display, it'll help to be familiar with some of these concepts. Check out our how to solder tutorial for help, if this is you first time soldering. That means you'll need at least a basic soldering iron as well as solder. In order to make use of the Serial 7-Segment Display, you'll need to solder to at least a few of its pins. Or, you could just go with a few pieces of wire. You could use a combination of male headers and breadboard. You'll also need some way to connect between the display and Arduino. In the Arduino's stead, you could use an FTDI Basic, or any device capable of sending TTL serial data.

Required MaterialsĪside from the display itself, you'll need an Arduino (or one of its variants) to send the serial data. The board is very easy to use since you can just plug it straight into an Arduino Uno compatible board and you can use the same exact code examples as the Serial 7-Segment Display which are covered in this tutorial. If you have the 7-Segment Shield, we recommend going to its tab first and beginning your journey there. This tutorial also covers the 7-Segment Shield. Given the popularity of Arduino, the examples will make use of the ubiquitous development platform/language. We'll cover hardware set-up, assembly, and example interface circuits/code.

The goal of this tutorial is to get you familiar with the Serial 7-Segment Display.
