And now something for those just starting to experiment with their Arduino boards - a great little kitchen timer project brought to us by Instructables user 'anonymouse197'. By using their Arduino, ten LEDs and other simple hardware along with a piezo buzzer - a customisable timer can be made. The LEDs are used to show the time left during operation, and also form part of the user interface. Watch the following video for more notes and a demonstration:
As always this project is open for modification, such as reducing the time periods represented by the LEDs or having it play a tune when the alarm activates. So to get started, click here. And we're on twitter and Google+, so follow us for news and product updates as well.
When making your own projects that require a buzzer or the ability to play a reasonable tune - use the Freetronics SOUND: sound and buzzer module:
This versatile piezo-element module can be used for both input or output! It can be used as a noise-maker driven by your microcontroller for audible feedback of events, and it can also be used as a knock-detector input to sense events and react to them. Includes a built-in 1M resistor to allow the piezo element to detect shocks. For more information and to order, click here.
