Tutorial 4: Remotely Control a Buzzer over the Internet

ioBridge’s technology is often used for real-time control over the internet.

This tutorial shows you how simple this is to set up using a Buzzer Board (FB-6) as the buzzer.

Project Components

Step 1 – Plug in a Buzzer Board

In this tutorial we are going to assume that we still have a temperature sensor plugged into channel 1 (from the earlier tutorials) although it is not necessary.

The first step is to plug in a Buzzer Board (FB-6) into Channel 2 of an IO-204 or Gamma. If you have a Channel Tester (FB-1) you can also plug it into the Relay Board to see if the relay is on or off. The Buzzer Board includes a buzzer that makes a tone when the channel output that it is connected to is high.

The Channel Tester (FB-1) if used shows the state of the relay and the red LED light up when the relay is off (NC and C connected, digital output low or 0) and the green LED is on when the relay is on (NO and C connected, digital output high or 1).

Step 2 – Create a Digital Output Pulse Control and Place it on a Dashboard

Sign In to your account at www.iobridge.com (or www.iobridgepro.com if you are using a PRO gateway). Click on the Widgets menu and then click on Create Widget. Select Digital Output Pulse and then click Next.

Select Positive Toggle and click Next. Select the gateway connected to the buzzer and click Next. Select Channel 2 and click Create Widget. Select Milliseconds (ms) and click Create Widget. You should then see a page similar to the one below. Change the Label to Buzzer, change the Button Label to Send Tone, change the Pulse Width (ms) to 250 (to send a quarter second pulse) and click on the + icon next to Dashboard to place your buzzer control on your dashboard.

Click on Dashboard on the navigation menu. You should now see your Buzzer control on your dashboard.

You can now click the Send Tone button to send a 250 ms tone to the buzzer. Note how fast it is!
