Updating wireless garage door controls with Arduino

 After giving 35 years of service the wireless remote system for perhof's garage door needed replacing, and instead of repairnig the old system they instead engineered and built a newer, secure system based on the Arduino platform. The new system uses inexpensive 433 MHz wireless transmitter/receiver sets that are easily available, and even though data only travels in one direction they have created a data protocol that not only keeps the system secure - is also an interesting example in itself. And power management has been taken into consideration, with the transmitter only drawing 0.1 uA when in standby. 

Very well done - for complete details including code and design, visit the perhof website. And for more, we're on twitter and Google+, so follow us for news and product updates as well.

If you're looking to work with your own RF wireless hardware, but don't want to make your own receiver circuit - check out our range of  315/433 MHz receiver shields:

Apart from being idea for working with the various low-cost data links on the market, the shield can also be used to capture wireless weather station data, as described in the book "Practical Arduino". For more information and ideas, check out the product page
