Hi,
I have a relay that controls a monostable 555 timer. The output of the 555 timer has 3 switches at the output that turn on a row of 4 led's, piezo buzzer and a DC motor. The circuit is configured to give 1.5 seconds at the output to operate each device similtaniously (can be switched on or off independently). The issue is i cannot seem to get the DC motor to pulse for 1.5 seconds (as it is just to provide a vibration, like the rumble in an xbox controller etc). The rating of the motor is:
Operating voltage 1.5 - 5Vdc.
Rated load 10 g.cm.
Speed@rated load - 5000rpm
Current@rated load - 450mA.
No load current - 130mA
The circuit runs from a 9V battery
Would i have to use a transistor and zenner diode? Any ideas woul dbe much appreciated.
