Using a 1000mA LiPo battery (that is nominal 3.7V) connected to the 5V pin, I was able to power all six vibe motors without any issues. It appeared to pull about 170mA from the LiPo battery. When plugging this into a USB port, it was able to provide more power (obviously). Each motor was pulling about 40mA from each of the Atmega328P 's pins and the benchtop power supply seemed to indicate that it was using ~240mA. Testing with the 3.3V Pro Mini using benchtop power supply set to 5V and connected to the raw pin, it appeared to pull about 152mA.</p><p>I would be cautious when using that many vibe motors because you might be slightly going over the absolute maximum ratings as suggested in the Atmega328P datasheet [ pg299 <a href="http://www.atmel.com/images/atmel-8271-8-bit-avr-microcontroller-atmega48a-48pa-88a-88pa-168a-168pa-328-328p_datasheet_complete.pdf" rel="nofollow">http://www.atmel.com/images/atmel-8271-8-bit-avr-microcontroller-atmega48a-48pa-88a-88pa-168a-168pa-328-328p_datasheet_complete.pdf</a> . To be safe, make sure to use a transistor to source power to the motor.</p></p>

Customer #140000 on DEV-11008 - LilyPad Vibe BoardCustomer #140000urn:uuid:c502f227-352d-c147-0c9c-aa2cc59018212015-02-16T07:51:17-07:00<p>You can control the intensity by changing the voltage between the positive and negative pins of the vibe motor. Just connect the vibe board to a analog pin and GND.
Use following code.
analogWrite(vibe, val);
Replace val with 0-255. See the data sheet for Vmin for determine the minimum value for val. Hope this help you.</p>

The motor draws 85mA when starting while Arduino pins are 40mA max.<p>What is needed is to connect the 5V of the Arduino to the vibe board, and control the motor actuation through an output pin via a transistor. A resistor is also needed between the pin and the transistor to limit current flowing through the pin when active.</p></p>

The motor is rated 75mA and 3V. (so when sourcing with the +5V, we need a resistor of at least 2/0.075 = 26.6Ω).</p>

What I'm finding is that at they will cut our for a few seconds or more at semi random intervals. So roughly every 2-3 minutes minute or so they'll stop working for say 5 seconds. I have 4 of these. Some are more susceptible to this problems then others. Any thought's as to what is causing this or how I might diagnose / prevent?<p>I have a suspicion that contact with skin, which can be mildly conductive, might be a factor. I'm considering making a tin shield around them...</p></p>
