The coin vibration motor (in our case the TC-9193500) is an Eccentric Rotating Mass vibration motor (ERM). An ERM uses a small unbalanced mass on a DC motor. The rotation of the mass creates a force that translates to vibrations.<br />
<br />
== Technical Specifications ==<br />
* shape: coin format<br />
* size: 10 x 2,7 mm<br />
* operating voltage: 3V<br />
<br />
== Advantages and Disadvantages ==<br />
=== Advantages ===<br />
* small size<br />
* simple to use and easy to control<br />
* translates to a wide range of vibration amplitudes and frequencies to match any application<br />
<br />
=== Disadvantages ===<br />
* its amplitude is tied geometrically to the frequency and the speed, so it is not possible to alter the amplitude and frequency independently<br />
<br />
= How to get it to work =<br />
== Microcontroller ==<br />
Use a microcontroller of choice. In our example below we use the [[Raspberry Pi Pico]]. <br />
<br />
== Wiring with a Raspberry Pi Pico ==<br />
* If necessary, solder cable ends to jumper cables<br />
* Connect the black cable to GND <br />
* Connect the red cable to GPIO<br />
* Be careful not to connect the two cables to prevent short circuits<br />
<br />
== Code Example ==<br />
<syntaxhighlight lang="python" line='line'><br />
<br />
# import modules<br />
from machine import Pin,PWM<br />
from time import sleep_ms<br />
<br />
# connect red to GPIO3 and black to GND<br />
vib = PWM(Pin(3))<br />
vib.freq(1000)<br />
<br />
# for a duty cycle with 16 bit define the maximal possible value <br />
max_value = 65535<br />
<br />
# for soft vibrations 30000 is a still visible value<br />
min_value = 30000<br />
<br />
# example vibration rhythm<br />
# play with the sleep_ms values to change the rhythm of the vibration<br />
# play with the duty_u16 value to define the intensity of vibration<br />
while True:<br />
vib.duty_u16(max_value)<br />
sleep_ms(1000)<br />
vib.duty_u16(min_value)<br />
sleep_ms(1000)<br />
