Further Development

Once you have experienced haptics with this kit, you may want to apply it to your own
projects. We have an extensive range of vibration actuators that can be found on our

website at precisionmicrodrives.com/vibration-motors and are available to purchase in

our online shop. However, if you are unable to nd what you are looking for or you need

some support, our engineers are always happy to answer any questions. Please contact

us using any of the methods shown below.

2 System Overview

The Haptic Feedback Evaluation Kit is comprised of two main hand-held units, the Haptic

Controller and the 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.
