Automatic Gate Control

[Slayerza]

Hi,
I need some ideas for a simple project. Here is the scenario. I have an automatic (motorized) sliding gate. In order to open the gate a simple RF reciever produces a pulse in order to open the gate. After a set time the gate closes automatically.

The problem is how to keep the gate open by using only the existing hardware and keep the interface wireless?

Cheers

hi
you can add delay and repeat it until a new pulse come from the RF OR
you can add a multivibrator to the sensor in the gate so the gate will open when a pulse come from RF and still open until a new pulse come then close so you control the time of openning and closing.
