Upload the following code to your Flora using the Arduino IDE. Change the 'interval' variable to your desired timer. Requires the DRV2605 library.
This basic code creates a variable delay between pulses-- adjust the 'interval' value to your liking.
For a more complex, power saving example, check out the Gemma Mindfulness Bracelet.
