This is a very simple project which could be used for an infinite number of different purposes! You could use your pressure plate switch to add perfect timing into your haunted house, automatically trigger your doorbell when someone stands on your doormat, track the presence of mail or parcels, or even set up your alarm clock to only turn off when you get out of bed and step on the switch! The switch is made up of two separated sheets of aluminium covered cardboard which connect when pressure is applied, closing the circuit.
The possibilities are really limited to your imagination. This project allows you to easily build something that is impressive and useful! The best thing about this project is that all you need to get started is some wire, aluminium foil and cardboard! To begin making your own pressure plate check out the following instructable from Jason.
To get the most out of your pressure plate switch why not add a Freetronics “Eleven” Arduino Compatible Board to your project so you can use the switch to easily control different outputs.
The Eleven is just like an Arduino Uno (and 100% compatible), however the Freetronics team have made a number of improvements to the Arduino Uno design such as adding in a prototyping area, using a micro-USB connector and more. These improvements mean that the Eleven is as easy to use as possible and is of the highest quality! To find out more about the fantastic Freetronics Eleven check out the following link. The Eleven has just come back into stock so order soon to avoid missing out!
