Hexiwear / Mbed OS Hexi_Click_Relay-v2_Example

Click Relay example for Hexiwear featuring Touch buttons and Haptic feedback

Dependencies:   Hexi_KW40Z

This project demonstrates the use of the Mikroelektronika Click Relay module with hexiwear featuring the Touch buttons and Haptic feedback

Plug Hexiwear into the Docking Station and the RELAY Click to the Click Socket 1
Connect the USB cable to your computer and to the micro-USB port of the Docking Station

Compile the project and copy the binary "Hexi_Click_Relay-v2_Example_HEXIWEAR.bin" in the DAP-LINK drive from your computer file explorer
Press the K64F-RESET button on the docking station to start the program on your board

Touch the left or right electrodes/buttons located below the screen to control the relay 1 or 2
Haptic motor will vibrate to acknowledge that a touch command has been received
RGB LED will briefly turn orange for Relay 1 and red for Relay 2 position change.
