As someone new to electronics, I initially hit a wall after making LEDs blink. The GrovePi Starter Kit was a big help to get past the initial barrier of learning to read data sheets and figuring out how to wire up the sensors.
I wrote a blog post about building a Home Weather Display with Nerves and GrovePi.
I also posted my All of the Lights project a few weeks ago which uses the GrovePi relay to turn a lamp on and off with Phoenix & Channels.
Both of these projects just use sensors from the starter kit and the grovepi library. The library includes a few other example projects using sensors from the starter kit (excluding the PivotPi which is sold separately).
