Customized LED displays are cool. You can change what they display whenever you feel like. Some use computer programs to change the displayed text while others come with a keypad attached on them that allows you to make the changes. These are good features, but what if I told you that you could change the display from your smartphone? Well, this is possible in this WiFi controlled led display demo I made.
- Arduino MEGA
- Wifly shield ($100)
- WS2812 neopixel Matrix
- Power supply/ battery
The key parts of this project are creating the HTML webpage, creating the Arduino code and setting up the hardware. Once everything is set up, you will be able to join a WiFi hotspot with your setup and be able to control what is displayed on the neopixel matrix from the HTML webpage on your phones web browser.
