# Haptic Headband

## Overview

https://youtu.be/xD7bfBx5D9M

Create a vibration notification wearable for timing your meditation sessions and so much more! The haptic motor controller can execute waveforms, taps, clicks, fuzzes, hums, and bumps-- different patterns of vibrating that you can recognize. Build it into a bandana or headband for a meditation timer that gently signals you without the need for your phone's alarm.

Before you begin, make sure you've read the following prerequisite guides:

- [Getting Started with Flora](../../../../getting-started-with-flora)
- [Adafruit Guide To Excellent Soldering](../../../adafruit-guide-excellent-soldering)
- [Battery Powering your Wearable Electronics](https://www.youtube.com/watch?v=U_Q3djsktQs)
- [Adafruit DRV2605 Haptic Controller Breakout](../../../../adafruit-drv2605-haptic-controller-breakout)

For this project you will need:

- [Flora microcontroller](http://www.adafruit.com/product/659) (or other I2C capable microcontroller)
- [DRV2605L Haptic Motor Controller](http://www.adafruit.com/product/2305)
- [Vibrating Mini Motor Disc](http://www.adafruit.com/product/1201)
- [Lipoly battery](https://www.adafruit.com/products/1317) and [charger](https://www.adafruit.com/products/1304)
- [Soldering tools and supplies](../../../../adafruit-guide-excellent-soldering)
- double sided foam tape or velcro tape (optional)
- Headband or bandana
- needle and thread (optional)

## Solder Circuit

![](https://cdn-learn.adafruit.com/assets/assets/000/028/701/medium800/flora_haptic-headband-02.jpg?1448458001)

Solder four wire connections as follows:

- motor controller VIN -\> Flora 3.3V
- motor controller GND -\> Flora GND
- motor controller SCL -\> Flora SCL
- motor controller SDA -\> Flora SDA

![](https://cdn-learn.adafruit.com/assets/assets/000/028/702/medium800/flora_haptic-headband-03.jpg?1448458046)

Solder the vibtration motor to the + (red) and - (blue) on the motor controller.

![](https://cdn-learn.adafruit.com/assets/assets/000/028/703/medium800/flora_haptic-headband-01.jpg?1448458096)

Use a piece of double sided foam tape (or velcro tape) to affix the moto controller to the back of Flora, and plug in your battery.

# Haptic Headband

## Code

Upload the following code to your Flora using the Arduino IDE. Change the 'interval' variable to your desired timer. Requires the [DRV2605](https://github.com/adafruit/Adafruit_DRV2605_Library) 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](../../../../buzzing-mindfulness-bracelet).

```auto

Basic timer circuit to trigger haptic motor controller at a specified interval.

*/

#include <Wire.h>
#include "Adafruit_DRV2605.h"

Adafruit_DRV2605 drv;

uint8_t effect = 7;
uint32_t wait = 10; // Time between reminders, in seconds

void setup() {
  Serial.begin(9600);
  drv.begin();
  
  drv.selectLibrary(1);
  
  // I2C trigger by sending 'go' command 
  // default, internal trigger when sending GO command
  drv.setMode(DRV2605_MODE_INTTRIG); 
  
}

void loop() {
  Serial.print("Effect #"); Serial.println(effect);

  // set the effect to play
  drv.setWaveform(0, effect);  // play effect 
  drv.setWaveform(1, 0);       // end waveform

  // play the effect!
  drv.go();
    
    
    delay(wait * 60 * 1000);
    

}

```

## Wear it!

![](https://cdn-learn.adafruit.com/assets/assets/000/028/704/medium800thumb/flora_haptic-headband-04.jpg?1448461626)

Plug in your battery, power Flora's switch ON, and roll up the circuit in a headband or bandana. Wear for timing your meditation, reminding you to check the laundry, etc.!
