Hello, everyone.
This question is so simple that it may sound complicated to all you knowledgeable folks here; please consider it's coming from a total newbie.![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
What is available:
- A vibration motor, runs at anything between 1.5V DC and 4.5V DC, < 100 mA
- An audio source, line-level (actually headphone level @ low volume)
- A power source providing minimum 3 Volts (a 3.7V battery pack)
What is to be accomplished:
- Spin the motor when there's any audio coming in (above noise level)
Basically, this "project" needs to close the circuit between the battery and the vibrator, and keep it closed for as long as there's audio at the input. Think of this as replacement of a speaker/buzzer with a vibrator: instead of hearing a beep, feel a vibration. Please imagine something as simple as possible... could it be a transistor / diode / relay / triac or any combination thereof? What values? (sorry if my suggestions seem silly
- remember my noobness)
Many, many thanks in advance!
