Making a stepper motor move is easy with an A4988 driver. They’re super straightforward and very versatile, making them very popular for 3D printers and other DIY CNC machines.
You want a robot to move when someone clicks a button on a RESTful website, and the robot reboots every time you click the web page. Here’s how I fixed it.

This is index of existing and future MarginallyClever Arduino Starter Kit tutorials.
From there we can get into lots and lots of other stuff, not in the scope of this kit:
Follow along and comment your questions. I’ll answer them and improve the tutorial based on your ideas.
What you see in the picture above is a piezoelectric speaker – a tiny, electrically controlled diaphragm. On the back is a small crystal. When there is power flowing through the crystal, the size changes, bending the diaphragm. The change in the diaphragm is what causes sound and music as we know it. Today, let’s go through how we can make music with a piezo and Arduino.
CanDo is a gentle introduction to robotics for anyone who’s just starting out with electronics or programming. It assembles in about 20 minutes and requires no soldering or wire stripping. Kits are $100.
Some arduino starter kits will teach you to turn on a light or move a motor and then expect you to figure out the rest by yourself. CanDo gives a bit more direction and a greater feeling of accomplishment, because when you will build your own robot. For those who still want to go even further, we offer this challenge: Can you improve on the CanDo to solve a maze?
Each CanDo comes with all the parts you need to build your robot. Just add a 9v battery and you’re ready to go!
