2 System Overview
The Haptic Feedback Evaluation Kit is comprised of two main hand-held units, the Haptic
Controller and the Haptic Grip:
Haptic Feedback Evaluation Kit
Haptic Controller
Haptic Shield
Haptic Grip
Arduino UNO R3
Haptic Controller
Together, the Haptic Shield and the Arduino UNO R3 make up the Haptic Controller and act
as the ‘brains’ of the system.
Arduino is an open source development platform for electronics, as a term it is colloquially
use to describe the parent company, the product range, or a speci c board. The UNO
R3 is based on the Atmel ATmega328 microcontroller, its stackable headers enable the
functionality to be extended by connecting customised boards, called ‘shields’, which
mate with the Arduino.
The Precision Microdrives Haptic Shield is specially designed for haptic feedback, with
capacitive touch buttons for input and a Texas Instruments DRV2605L haptic driver and
MOSFET for vibration output.
Haptic Grip
The Haptic Grip houses 4 di erent vibration actuators to enable users to experience
a range of haptic feedback and vibration alerting, including 3 ERMs (304-103, 306-109,
308-102) and the C10-100 LRA.
This makes it easy to compare haptic e ects against each other and feel the e ects
independently of the Haptic Controller. It is designed to have a form factor that can
represent a variety of end applications, such as hand held instruments or joystick
interfaces.
A PDF reference is available at precisionmicrodrives.com/haptic-kit which lists key
parameters of each motor included, with space for notes about other actuators you may
use.

3 Setup & Installation
The Haptic Feedback Evaluation Kit arrives completely assembled with all hardware
provided in the box. To start, simply connect the kit to one of the power sources outlined
below.
Power
The Arduino allows you to supply power via the USB port or DC connector. You can use
either option. However, please note that old versions of the Haptic Shield must be powered
via USB only. If this Quick Start Guide was supplied with your kit, you have the new version
and may proceed with your preferred choice. If you are reading this online, you should
double check your version of the Haptic Shield by visiting precisionmicrodrives.com/
haptic-kit.
If using a USB port on a computer or laptop to power the unit you may be subject to
current limiting on the USB port. You will need to install the Arduino drivers to correct
this. When the actuators are vibrating the current draw can peak over 100mA. By installing
the drivers the Arduino is able to negotiate up to 500 mA. Not installing the drivers risks
limiting the current to the motors, thereby reducing the performance and in some cases
not allowing the kit to start-up.
(In some computers, particularly laptops, several USB ports can use the same internal
power supply. If possible, remove other USB devices that may be connected to the same
line as the kit.)
Drivers and Software
Installing the drivers and sof tware for the Arduino Uno R3 is simple, but they are updated
periodically. Therefore it is best to get the latest version and instructions from the Arduino
website (note URLs are case-sensitive):
l Navigate to arduino.cc/en/Main/Software or search ‘Arduino software’
l Install the Arduino software, includes drivers and IDE (1.8.7 at time of release)
l Refer to the Getting Started page for more help arduino.cc/en/Guide/HomePage
Existing Arduino Users and Kit Owners
If you already have the Arduino IDE installed, we recommend ensuring you upgrade
to the latest version. If you wish to continue using an older version, please visit
precisionmicrodrives.com/haptic-kit for legacy support.
For owners of the Rev1 kit, please ensure you replace the libraries with the Rev2 versions.
For full upgrade instructions, please visit precisionmicrodrives.com/haptic-kit.

4 Intro Mode
The Intro Mode rmware is loaded onto the Haptic Controller prior to shipping. After
successfully completing the installation process and providing power, the kit will
automatically start and the Precision Microdrives logo will appear on the OLED main
screen.
Intro Mode serves as an introduction to haptic feedback and vibration alerting. This makes
it perfect for those who are unfamiliar with haptics, or for demonstrating to colleagues the
value of the features. Even if you are experienced with haptic feedback, you may wish to
explore the tutorials to discover some of the additional features of the DRV2605L.
There are four tutorials in the Intro Mode,
use the Left and Right buttons to move
between them.

Press the Select button to start:
l Quick-Start Demo
l Haptic Feedback Tutorial
l Vibration Alerting Tutorial
l DRV2605 Overview
Develop Understanding
Each tutorial has several slides for you to read about the concepts demonstrated. They
are easy to follow and you can go back by pressing the Left button, or exit with the Back
button.
Feel Eects
At specic points in each tutorial you will be prompted to press the Play button. Dierent
eects are played on the Haptic Grip or the Haptic Controller, you can repeat them by
pressing the Play button a second time.
Apply
Not only will the tutorials walk you through the concepts of vibration alerting and haptic
feedback, some also include example applications. Start thinking about how you would
use haptics to improve your product, then try out the Engineering Mode.
5
5 Engineering Mode
The Engineering Mode uses dierent rmware that needs to be loaded into the Arduino,
to perform this you will need to have installed the Arduino Environment (see Section 3)
and have downloaded the code from precisionmicrodrives.com/haptic-kit. It gives access
to a greater range of eects and functionality.
It is also recommended you read the Section 5 of the User Manual to get the most out of
the Engineering Mode. The User Manual is available online at precisionmicrodrives.com/
haptic-kit.
Upload the Code
To enter the engineering mode, you need to compile and upload the code
through the Arduino Environment. Downloaded and extract the code to your
chosen folder, open the EngineeringMode.ino le (.ino les are called ‘sketches’).
Supporting les called ‘libraries’ are included in the zip, ensure the Sketchbook
Location (File -> preferences) points to the folder above the libraries folder. If
everything is correct you can click the 'upload’ button. More detailed instructions
available in the User Manual or at precisionmicrodrives.com/haptic-kit.
Using True Haptics
Here you can experience haptic feedback through the DRV2605 which includes 123
dierent haptic eects and 6 libraries. Navigate clicks, bumps, pulses, and many more
options.
Press the Play button to play the chosen eect and press the PMD button to cycle
actuators. The True Haptics Menu Map and Eect ID Table (Sections 9 and 10) will help you
nd eects quickly.
Using Vibration Alerting
Vibration alerts can be played through the on-board MOSFET and PWM. Build your own
vibration alerting waveform by setting each variable in the Vibration Alerting section,
including vibration power, vibration waveform, on time, and o time. Please note that
LRAs require an AC signal, so cannot be played by the on-board MOSFET.
Keep Developing
Try using the DRV2605 librar y and example code to start prototyping your own system.
The Arduino can be used to accept inputs, the library lets you easily interface with the
DRV2605, and you can connect to an external actuator using the terminals on the Haptic
Shield.
6
6 Development Mode
Having approached haptics with the Intro Mode and gained a more in depth idea of what
our motors can do through using the Engineering mode, you may be thinking about how
you can develop this into your own project.
The Development Mode has been created to allows designers to implement haptics using
our Haptic feedback kit. You can download the rmware from precisionmicrodrives.com/
haptic-kit.
Modifying and uploading the code
All the software needed to run in our Haptic Kit is available on our website and users
can deal in the Software without restriction, including without limitation, the rights to use,
copy or modify it.
The Development Mode program is used to start writing your own code. It handles
the initialisation of the pins, I
the DRV2605 Arduino Library Reference useful, but those unfamiliar with Arduino
programming may nd the tutorials and examples more benecial.
To upload the code in the kit, follow the same instructions as in the Engineering
Mode. This will give you complete access to the open source code. The motors
are driven using the driver DRV2605 from Texas Instrument. The Development
Mode will allow you to program the driver and choose the setting that best
suits your application and the PMD motor you are using. You can refer to
Texas Instruments (TI) to understand the features of the driver and map of addresses.
You can connect an external actuator to the kit using the green screw terminal
and program your own patterns, eects and recurrences. It is also worth noting that the
OLED display is disabled in the Development Mode as it is designed to be very simple. This
means that nothing will appear on it and the pins that were required to drive it are now
available. The Pin Mapping in section 8 will help you identify which pins are free.
