Some ideas to consider
We use this web server to solve puzzles using the Raspberry Pi. It can be useful to sharpen

Building a science fair exhibit using
the Raspberry Pi
In this task, we will build a simple physics experiment controlled by the Raspberry Pi. This
can be used to explain how things such as a solar panel, windmill, and so on work. In this
example, we will build a windmill experiment that can possibly be used as a demonstraive
exhibit at a science fair.
Prepare for lift off
We need a windmill generator kit from a hobby s
tore (for example,

). The kit needs to be put together leaving the leads of the DC motor exposed.
Engage thrusters
1.
The DC motor of the wind energy kit needs to be interfaced to the Raspberry Pi
GPIO pin as shown in the following Fritzing schemaic:
