For building apps to remotely control electronic objects using Arduino, an open-source electronic hardware platform that allows the creation of interactive electronics, Ember and Torch is a perfect fit to help turn nearly any device into a "remote control to your world," according startup developer Lava. These Bluetooth low-energy Arduino-compatible boards will talk directly to any smartphone, tablet or computer. The low-energy Bluetooth enables out-of-the-box connectivity for devices and Lava's software library, called Bonfire, which substitutes as a bridge between an app and the hardware project. Bonfire can run on Arduino, Android, iOS and OS X. Some sample apps include Joysticks, for remote-controlled cars; Color, an RGB light strip controller; Outlet, for electrical outlets. Currently, Bonfire isn't compatible with Android. But, it works with iPhone 4S and above, iPad 3 and above, iPad mini, iPod 5th gen, MacBook Air mid-2011 and above, Mac Mini mid-2011 and above, MacBook Pro 2012 and above and iMac 2012 and above. To date, there are 155 backers that have pledged $8,668 of the $80,000 goal. The funding period ends July 11, 2013.
