The arrival of the External Accessory Framework was seen, initially at least, as having the potential to open the iOS platform up to a host of external accessories and additional sensors. Sadly, little of the innovation people were expecting actually occurred, and while there are finally starting to be some interesting products arriving on the market, for the most part the External Accessory Framework is being used to support a fairly predictable range of audio and video accessories from big-name manufacturers.
The reason for this lack of innovation is usually laid at the feet of Apple’s Made for iPod (MFi) licensing program. To develop hardware accessories that connect to the iPod, iPhone, or iPad, you must be an MFi licensee.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
