Get started making tiny Arduino projects with the Ardweeny Starter Pack! There's no need to leave your full Arduino board in your project since it's great for prototyping, just drop in an Ardweeny which is about 1/3 the cost and much, much smaller.
Sometimes, voltages collide. When you have parts that expect/speak at different voltage levels, you have to build a mediator to smooth things out. This SparkFun BOB-10403 uses PCA9306 two-channel bidirectional voltage-level translator on a nice, small breakout board.
