Start with trying out a standard servo. To be able to control a servo with Arduino you will need to use the Servo library. As explained in block 2, a library is a collection of code that you can call from your own code.

Continuous rotation servo
Try out the continuous rotation servo. You control the continuous rotation servo by writing a speed to it instead of a position.
Input Controlled Servo
You can use any kind of input to control a servos.
Crawling robot
This small robot can crawl. It is all it can do, and it is not very good at it. But it is super cute and great fun.
Camera robot
Spy on your cat with this robot camera. Mount the camera robot and control it with a small joystick. You can watch the camera image on the computer and when you see your cat doing something suspicious, take a picture!
Open box
OpenBox is an open source box that contains open source electronics. Oh, and it automatically opens when you knock on it.
Light chaser
This little vehicle is on an impossible, never ending mission to catch the light. You can make it follow you by pointing a flashlight at it, e.g., the one on your mobile phone. It will always turn towards the light.
Tickle Robot
This is just a regular ticklish robot in a rocking chair. Come to think of it, that does not sound very regular at all. Tickle the robot on its heart and it will start to wiggle like crazy.
Using Two Servos
When using two servos at the same time, your Arduino board will have a problem distributing enough current. There are different techniques to overcome this. Here you will explore how to write signals to the servos separately through the program. Go here to learn about how to use two servos as wheels.
Types of Motors
You are going to use the Arduino board to control motors. Many electronics that have moving parts contain motors, e.g., printers, car toys, electric toothbrushes. While there are many different types of them, you will mostly find the following three types of motors:
Robots
The robot block is finally here. In this block you will build different robots using motors. The basic function of these motors is simple; they spin. You will see that depending on how you decide to use them, you can get different objects to animate in many different ways. First of all, you will get an introduction to the different types of motors there are and some examples of when to use them. In the end of block 4 you will get to build a ticklish rocking chair robot or maybe a light chasing robot.

Line Follower
The Line Follower does exactly what the name suggests, it follows a line. Make it go where ever you want by showing the way with a 3 cm wide, black line.
