There are a few ways to get into lighting. A good start is with LEDs, which are cheap, easy to use, and safe (low voltage). An ordinary Arduino style board comes with an on-board LED you can turn on and off (this is how a lot of people get started). After that, you can add external LEDs (along with current limiting resistors) for more LEDs. You can also look at addressable LEDs, which let you send commands to them to set their color and brightness. You can hook a bunch of them to a single controller. There are also LED strips without controllers, so you can control large numbers of LEDs at once using transistors. Another route is boards like AdaFruit's Circuit Playground Express (which has several addressable LEDS built in), and the new Crickit, which includes an addressable LED interface, as well as motor and solenoid drivers, for when you want to branch out. You can even use the motor drivers to control stepper motors.
