LED Table @ FFII

This is a 20x14 Pixels LED table. Each of the pixels can display almost all colors.

You can play the game with the controllers. It is in ffii.ino on this page. You will need to upload it, see Programming. If you would like to see the making of the LED table, you can visit Youtube. If you have any questions, you can leave a comment below or contact me via email.

Usage

To use the LED table you can plug it into the power plug in the wall. If you would like to use the controllers, one of their ends should be plugged into A0 or A1 or A2 or A3 on the Arduino and the other end into Ground or GND or the blue line on the breadboard. You will notice if they are not plugged in correctly: They will not work. In rar cases where you connect 5V and ground directly to eachother, you will melt the cables or destroy the Arduino. Do not do that.

Original solution sacrifices new api lint check.

Here my solution:

int minSdk = hasProperty('minSdk') ? minSdk.toInteger() : 16

apply plugin: 'com.android.application'

android {
 compileSdkVersion 23
