what would be the easiest way (with minimum components) to control an array of 16 vibration motors (3V, <100mA each)? on/off, no pwm is needed..
motor's datasheet: http://www.sparkfun.com/datasheets/Robotics/310-101_datasheet.pdf
ULN2803, 2 IC. Why do you think you need multyplexing, not enough pins? Most boards have 20 and more.
thanks!
yes, i was going to go multiplexing, as i'm using the teensy 2.0..
Shift registers serial in / parallel out work well as digital port extenders, 74HC595 for example. Or you can use TPIC6B595 instead of 74HC595+ULN2803 couple.
