Crowtail- Haptic Motor
Contents
Introduction
The Crowtail-haptail Motor is using little DRV2605 motor driver form TI. Its designed specifically for controlling haptic motors - buzzers and vibration motors. Normally one would just turn those kinds of motors on and off, but this driver has the ability to have various effects when driving a vibe motor. For example, ramping the vibration level up and down, 'click' effects, different buzzer levels, or even having the vibration follow a musical/audio input.
Mode: CRT00349H
Features
- Specifically for controlling haptic motors- buzzers and vibration motors
- Follow a musical/audio input
- Support LRA (Linear Resonance Actuator) and ERM (Eccentric Rotating Mass)
- Works with both 3V and 5V power/logic
Specification
- Dimensions(mm):20.0(L)x20.0(W)x6.8(H)
- Crowtail IIC interface
- motor : round or flatte 10*2.7MM
- using little vibration pancake ERM
Uager
We have set the pin to IIC interface and have a library for you to use, so it's usage pretty simple.
1.Hardware Connection
Connect the Crowtail- Haptic Motor to IIC port of the Crowtail - Basic Shield using a 4 pin cable .Then connect Arduino to PC by using a USB cable.
2.Softwart Connection
Download DRV2605 library for Arduino boards; Unzip and put it in the libraries file of Arduino IDE by the path: ..\arduino-1.0\libraries;
Upload it into your Arduino board and observe the vibration of the motor.
#include <Wire.h> #include "DRV2605.h" DRV2605 drv; void setup() { Serial.begin(9600); Serial.println("DRV test"); drv.begin(); drv.selectLibrary(1); // I2C trigger by sending 'go' command // default, internal trigger when sending GO command drv.setMode(DRV2605_MODE_INTTRIG); } uint8_t effect = 1; 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(); // wait a bit delay(500); effect++; if (effect > 117) effect = 1; }
