Introduction: Wi-Fi Controlled Bat Signal

Batman is the vigilante protector of Gotham City in the DC comics universe. He is also the alter ego of billionaire Bruce Wayne. The Bat signal summons Batman telling there is trouble and calling him to action. This instructable teaches you how to make a Wi-Fi controlled bat signal using a link it one.

Step 1: Materials

To construct your Bat signal you will need

  • LinkIt ONE Board
  • White LED
  • Index Card
  • Pen
  • Scissors
  • Glue Stick
  • Breadboard
  • 1kΩ Resistor x1
  • 330Ω Resistor x1
  • Transistor
  • WiFi/Bluetooth Antenna
  • Cardboardx2
  • Transparent Plastic
  • Kabob Stick x4

Step 2: LinkIt One

The LinkIt ONE is a microcontroller board developed by MediaTek. It has built in connections for Wi-Fi, Bluetooth, GSM and GPS antennae in addition to Arduino compatibility. This instructable takes advantage of the Wi-Fi capability.

Step 3: Let's Begin!

On one of your pieces of cardboard cut out a large circle, leave the other one alone for now.

Step 4: Attach the Transperant Plastic

Using the glue stick attach the plastic around the hole. Cut off any access hanging over the sides. of the cardboard piece.

Step 5: Making the Logo

Draw and Cut out the bat symbol from the index card, using the glue attach it to the transparent plastic.

Try to get it as close to the center as you can.

Step 6: Mounting the Signal

Using the kabob sticks poke holes in the cardboard piece.

Line up the holes and do the same with the signal piece.

Step 7: Connection

Push the kabobs through both pieces creating a stand.

TIP: Try to get the two cardboard pieces about 5 in apart, and cut the kabob sticks down to size.

Step 8: Circuit

Now that our stand is done we have to create the led circuit.

The circuit modeler I used doesn't have the LinkIt ONE yet so I put an Arduino as a stand in

With the LinkIt one you must connect the Wi-Fi antenna to the port on the bottom

Step 9: Code & Setup

Download the attached code to your LinkIT ONE

replace WiFiName with the name of your wifi, and PASSWORD with your password, etc.

Navigate to this link

Create an account and create a new prototype

Click details on the prototype and add a data channel

Set the channel as a controller

Next add a test device

Step 10: Done

Congratulations! In this instructable you learned how to code and create a WiFi Controlled Bat signal, in addition to getting an introduction to the MediaTek Cloud Sandbox
