Arduino Tutorials - By Component

The SparkFun Inventor's Kit (SIK) is a great way to get started with programming and hardware interaction with the Arduino programming language. The SIK includes everything you need to complete five overarching projects consisting of 16 interconnected circuits that teach everything from blinking an LED to reading sensors. The culminating project is your very own autonomous robot! No previous programming or electronics experience is required to use this kit. 

SparkFun Inventor's Kit Experiment Guide - v4.1

This is multipurpose PCB works with Arduino Nano. It is designed to run 2 Stepper motors, 2 DC motors, 2 Servo motors at same time. You can also connect a BT module, rotary encoder, I2C device, and potentiometer at same time. This PCB is helpful in building many projects and removes the need to worry about lots of messy wire connections.
