Create a simple buzzer by department

[spanky]

This guide will explain how to create a simple buzzer with little money.
First of all, buy a buzzer for intercom, available at any electronics store. The model and the voltage does not matter, in my case I used one of Ulmet the cost of 6 euros.
Obtain a telephone cable with 4-pin connector (make sure it has all poles connected to the cable)
Connect the den that corresponds to pin 2 partedno left the buzzer positive and the negative to pin 4 (see photos)
Place the beginning or end in the print pattern that interests us the following command <XCT 27,112,48,100,200>
The game is done
The command will only send a pulse to the gate of the money drawer which will sound the buzzer
You can increase or decrease the length of the sound playing with the last two numbers of the command, or you can add more commands to emmettere more sounds.

Hi,

Is this continuous beeping? I would like to make this for kitchen. I would like to have it beep for like 10-15 seconds.

Thanks,
Sukasem

You should enter several commands in sequence and change the penultimate number from 100 to 200.
<XCT 27,112,48,200,200>
<XCT 27,112,48,200,200>
<XCT 27,112,48,200,200>

but risks so that the paper comes out after a while.
