Coin Type Micro Vibration Motor

Coin Type Micro Vibration Motor Documentation

Overview

The Coin Type Micro Vibration Motor is a compact, low-power vibration motor designed for use in IoT devices, wearables, and other small form factor applications. It provides a gentle, subtle vibration feedback and is ideal for applications such as haptic feedback, notifications, and gaming.

Technical Specifications

Operating Voltage: 1.5V - 3.6V
 Operating Current: 50mA - 100mA
 Vibration Amplitude: 0.5G - 1.5G
 Frequency: 100Hz - 200Hz
 Dimensions: 10mm x 3.5mm x 2.5mm

Pinout

The Coin Type Micro Vibration Motor has three pins:

VCC: Positive power supply
 GND: Ground
 VIB: Vibration control pin

Code Examples

### Example 1: Simple Vibration Control using Arduino

This example demonstrates how to control the vibration motor using an Arduino board.

Hardware Requirements

Arduino Board (e.g., Arduino Uno)
 Coin Type Micro Vibration Motor
 Breadboard and jumper wires

Software Requirements

Arduino IDE (version 1.8.x or later)

Code
```cpp
const int vibPin = 2;  // Vibration control pin connected to digital pin 2

void setup() {
  pinMode(vibPin, OUTPUT);
}

void loop() {
  // Vibrate for 500ms
  digitalWrite(vibPin, HIGH);
  delay(500);
  
  // Stop vibration
  digitalWrite(vibPin, LOW);
  delay(500);
}
```
In this example, the vibration motor is connected to digital pin 2 of the Arduino board. The `setup()` function sets the vibration control pin as an output, and the `loop()` function toggles the vibration motor on and off every 500ms.

### Example 2: Voltage-Controlled Vibration using ESP32

This example demonstrates how to control the vibration motor using an ESP32 board and variable voltage levels.

Hardware Requirements

ESP32 Board (e.g., ESP32 DEVKITC)
 Coin Type Micro Vibration Motor
 Breadboard and jumper wires
 Potentiometer (optional)

Software Requirements

ESP32 Arduino Core (version 1.0.x or later)

Code
```cpp
const int vibPin = 25;  // Vibration control pin connected to digital pin 25

void setup() {
  pinMode(vibPin, OUTPUT);
}

void loop() {
  int voltageLevel = analogRead(A0);  // Read voltage level from potentiometer (optional)
  int vibrationLevel = map(voltageLevel, 0, 4095, 0, 255);
  
  // Set vibration level using PWM
  ledcSetup(0, 50, 8);  // Channel 0, 50Hz, 8-bit resolution
  ledcAttachPin(vibPin, 0);
  ledcWrite(0, vibrationLevel);
  delay(20);
}
```
In this example, the vibration motor is connected to digital pin 25 of the ESP32 board. The `setup()` function sets the vibration control pin as an output, and the `loop()` function reads the voltage level from a potentiometer (if used) and maps it to a vibration level between 0 and 255. The vibration motor is then driven using pulse-width modulation (PWM) to achieve the desired vibration level.

Note: The above examples are for illustration purposes only and may require modifications to suit your specific use case. Always ensure proper power supply and motor control to avoid damage to the motor or other components.
