Bill of Material

  • Microduino Equipment
  • Software Appliance
Arduino IDE(1.0 version and the above). Head for App Store to download and install LightBlue;
  • Other Equipment and Devices
  • Support IOS devices of Bluetooth 4.0( above iPhone 4s, iPod touch 5, iPad 3, and iPad mini);
  • MicroUSB cable.


Program to download:


Step 1: Start Arduino IED, open the test program that Microduino provides,and the board card choose Microduino Core (Atmega328P@16M,5V);
Step 2: OverlayMicroduino-USBTTL,Microduino-Core, andMicroduino-BT. Then plug MicroUSB to download the programs.
Step 3: Begin to set up IOS device,and initiate the Bluetooth function of the IOS device;
Step 4: Open LightBlue,find out “Microduino” in “Peripherals Nearbyl” tab control, and clock it to start connection.
Step 5: After connecting successfully, the LED indicator light will light for 100ms every 5 seconds,and you can see the connection state in ISO. Then slip to the bottom, and choose “Characteristic 6”;
