A BLUETOOTH GARAGE DOOR, TAKE three

A few years ago, [Lou] came up with a quite smart develop to open his garage door with his phone. He just took a Bluetooth headset, replaced the speaker with a transistor, as well as connected the transistor to a few wires coming out of his garage door opener. When the Bluetooth headset connected, the short beep coming from the speaker output opened the door.

The newest version of this build does away with the easy Bluetooth headset as well as replaces it with a Bluetooth 4.0 chip. The reason for this is that Apple as well as their walled garden of an app store would never enable a Samsung Bluetooth headset to be utilized with one of their iDevices.

The newest develop is just about as easy as utilizing a Bluetooth headset. A board that appears to utilize TI’s CC2540 chip is connected to the garage door opener with a few passives as well as a transistor. Pairing the new circuit with a phone is as easy as shorting a pair of pins, as well as the new iOS app does precisely what it ought to – opens a garage door at the press of a non-button.

While it’s not something that can be put together with scraps from a junk drawer, it’s still an incredibly easy service to opening a garage door with a phone. video below.
