    What day to day use does this have?

    •  

      A number of purposes for the geek out there. For example could use it in combination with an Arduino and a distance sensor to make a garage parking light e.g. green when close, yellow for even closer, and red for stop. Of course a tennis ball on a string is possibly better and cheaper, but that's beside the point. ;-)

      If you're asking the question you probably don't need them. That said below are some use cases for them. Just buy them from elsewhere.

      I bought some of the traffic lights for a status indicator project. It allows me to see the status of a bunch of services at a glance.

      The NRF24L01 lets you send serial data over 2.4Ghz. I've never used one.

      The Christmas trees are good for learning soldering. I built one with my son a couple of years ago. It is a straight forward project with a bunch of components.

        FWIW I use the NRF24L01 with mysensors.org modules for home automation - costs about $5 to make a battery powered door/temp/etc sensor.
