If you work in a company that has a website, you know how important it is that the website always be up and running. That’s why you constantly see “99.99999% reliability!” all over the fancy server hosting sites. A website can’t make money if the system is down, so knowing when that happens and reacting quickly is super important. In this Instructable, we will use the LinkIT ONE board to make an alert system that will play a loud alert siren and send us a text message. This way no matter where we are, we can respond as fast as possible!
Step 1: Supplies
Since we’re harnessing a lot of the built-in power of the LinkIT ONE, we don’t need that many external supplies here. You can focus your gathering energy on a quality speaker to play our alarm through!
- LinkIT ONE
- Speaker (headphones for testing is cool)
- SIM Card (Pre-paid for deployment, borrow a friend’s for testing)
- An Alarm MP3 File
- A Website to check on!
Step 2: Configure your LinkIt ONE Board
1. Set the MS — UART switch to UART (You’ll switch it to MS in a later step temporarily, but not for deployment)
2. Set the USB — BAT switch to USB
3. Set the SPI — SD switch to SPI
Step 3: Connect your GSM and WiFi Antenna
Now, you’ll need to make sure and connect both your WiFi and GSM antenna’s to your LinkIT ONE board. Both of these Antenna’s should have come with your LinkIT ONE kit. Attaching them is pretty self-explainatory: Connect the WiFi Antenna do the socket labeled ‘WiFi‘ and your GSM Antenna (Which allows you to send text messages) to the socket labeled ‘GSM‘
