Arduino with Bluetooth 4.0 Shield – iPhone Controlled Relay

After searching for a while I finally found an Arduino Bluetooth 4.0 shield from RedBear. My main aim was to able to control an Arduino from iPhone using Bluetooth 4.0.

Today I used SainSmart 8 Channel DC 5V Relay to play around. This relay is very easy to use with Arduino / Raspberry Pi.

To play around with the BLE shield I used the iPhone app and the Arduino code mentioned on their website. You should be able to follow the instruction and design your needed circuits to control. In my case the final setup looked something like this

Small video demo to see the above setup in action 😉

Stay tuned for more updates as soon as get time to work on these exciting projects 😉

  1. Hi,

    Does it have to be the RedBear BLE’s that you use? They are hard to come by in the UK, I’ve order another variant of bluetooth shield, but I want to be able to use my iPhone to receive data from my Arduino
