Raspberry Pi to Arduino shield thermostat – a sneak-peek

Here is a sneak-peek of the Raspberry Pi to Arduino shield based thermostat project I have worked on for the upcoming book.

The prototype you see below is part of a project in one of the chapters:

This uses a relay shield attached to the Raspberry Pi to Arduino shield. The relays are then switched on and off based upon a change in temperature. Connected to the relay shield is a wall powered electric fan.

Enjoy!
