Vibrator motor... 2

[aware]

Hi all,

I have created a little RF transmitter/receiver module (with encoder/decoder). The decoder is the following and of hi quality (R-8PD 4-Bit Decoder IC,

http://www.rentron.com/remote_control/Holtek.htm#R8P)

Now, the DataOut of the decoder has +3v when signal is sent by the transmitter. This is ok but if I connect a LED to the DataOut&GND then the LED turns on (good news) BUT when I connect a vibrator motor (

the vibrator doesn't activate (bad news).

Since I need to activate this vibrator motor my questions are:
1) Why although the voltage is OK, the vibrator motor isn't acivated?
2) Is it a matter of some extra circuit? What should this circuit consist of and how may I construct it? Any schematic would help so much.

Thanks for the reply. I followed the schematics on the datasheet and the vibrator motor works ok.

However, I face an issue: whenever the signal is sent, there is a time delay of approx. one third of a second until the vibrator is activated.
Is there a way to minimise or eliminate this delay please?

"one third of a second" based on what measurements?

If a human is involved what would 300ms matter?

it matters in my case, but anyway I found my fault about the 300ms - it was actually some loose connection that was responsible. Now, after fixing this, the delay is much less and almost unimportant to my project.
