Experiment Guide for the SparkFun Tinker Kit
Introduction to the SparkFun Tinker Kit
This SparkFun Tinker Kit Experiment Guide is your map for navigating the
waters of beginning embedded electronics, robotics and citizen science
using the SparkFun RedBoard while sticking to a strict budget. This guide
contains all the information you will need to explore the 11 circuits of the
SparkFun Tinker Kit. At the center of this guide is one core philosophy –
that anyone can (and should) play around with cutting-edge electronics in a
fun and playful way while not breaking the bank.
When you're done with this guide, you'll have the know-how to start
creating your own projects and experiments. From building robots and
game controllers to data logging, the world will be your oyster. Now enough
talking – let's start tinkering!
Included Materials
Here are all of the parts in the SparkFun Tinker Kit:
• SparkFun RedBoard – Our tried and true version of the Arduino
UNO.
• Breadboard – Excellent for making circuits and connections off the
Arduino.
• SparkFun Mini Screwdriver – To help you screw your RedBoard
onto the holder.
• Hobby Gearmotor Set – A set of hobby level motors with gearboxes
set to 120 RPM.
• Small Servo – Here is a simple, low-cost, high-quality servo for all
your mechatronic needs.
