Introduction
The end result of this project is a traffic light that shows the status of a software build.
It can show the following statuses:
- green: build is OK
- yellow: build compiles but a unit test fails
- red: build has failed to compile
- yellow flashing: build status unknown, e.g. still starting up, connection problem, or we receive a status we don't understand
Hardware
The plan is to use an ESP8266 (e.g. Wemos D1 mini) along with a modified toy traffic light (see below). Perhaps I'll need some kind of LED or bulb driver too.
Bonus point if we can add sound when the status changes.
This one has been ordered, to be modified with the ESP8266.
Software
ESP8266
Source code can be found here.
It is written in C/C++ for Arduino for quick and easy development using existing libraries, like WifiManager, PubSubClient.
The plan is to simply listen to an MQTT stream. To keep things secure and secret as much as possible, I plan to use an encrypted link to the MQTT server along with a username/password.
