Grove - Haptic Motor

Grove - Haptic motor is a grove module integrated with DRV2605L which will give your project more feelings. This motor is specially designed for various effects, such as ramping the vibration level up and down, for wearables and other IoT devices. Right now we have developed an easy-to-use library which simulate 123 kinds in total of vibrating modes and this will make your prototyping quicker. Also, you can develop more advanced functions with driver DRV2605L which will improve actuator performance in terms of acceleration consistency, start time, and break time and is accessible through a shared I2C compatible bus or PWM input signal.



Operating voltage 3.3~5.0 V
Ripples (at maximum power) 50~100 mV
Max power 750 mW
I2C speed 100 kHz
Vibration effects 123 types
Driver DRV2605L
Port I2C
Default I2C Address 0x5A

Application ideas

Hardware Overview

Getting started

Note that this section only shows you how to build a basic development environment. You can build a development environment for your project with following guides:

Build IDE

Refer to following guides to building an appropriate IDE:

Getting Started on Windows

Getting Started on Mac OS X

Note that Arduino board will also be fine if you happen to have no Seeeduino board because Seeeduino is compatible with Arduino.

Hardware connection

Note that make sure you have built a development environment successful through previous steps.

Note that make sure your board has selected Arduino Uno and COM port right chosen. Connect to I2C interface on Seeeduino board and Haptic motor with grove wire.

Download sample code

  1. You can download sample code and library or header files.
  2. Click a button named "Download Zip" at Github.
  3. Decompress the downloaded ZIP file.
  4. Remove the "-master" twice in decompressed file name.
  5. Copy the folder Grove_Haptic_Motor into your library folder (In default, it is same with Sketchbook Location which can be found by clicking File > Preference).Under Windows, it will likely be called "My Documents\Arduino\libraries". For Mac users, it will likely be called "Documents/Arduino/libraries". On Linux, it will be the "libraries" folder in your sketchbook.
  6. Copy file drv2605.cpp and file drv2605.h to its parent directory.

Load sample code

Note that in this case we use Seeeduino 4.2 as experiment board which is a compatible board with Arduino.

Tip: You can use Base shield v2 as expansion board which will make your connection of modules simple.

Note that never touch driver DRV2605L which may cause damage to it while it get power connected.

  1. Make sure haptic motor and main control board well connected.
  2. Load your sample code drv2605.ino under example file of decompressed file.
  3. Flash your code to your main control board by click Project>Upload(CTRL+U).
  4. After uploading, you now get haptic motor vibrate at a smooth style.
