Arduino Program to turn on Diagonal LEDs

          We have seen the programs to control individual LEDs of a 2*2*2 LED cube using arduino in the last few blogs. Circuit is done as shown in the following image.

          But it becomes difficult, if you want to turn on two diagonal LEDs together (LED 5 and LED 3 or LED 1 and LED 7 or LED 2 and LED 8 or LED 4 and LED 6). Let us analyse one example.

          If you want to turn on LED 5 and LED 3 together, positive voltage should be supplied to the "e" and "f" terminals of LED cube and negative voltage should be supplied to the "a" and "d" terminals of LED cube. The effect will be, LED 1, LED 3, LED 5 and LED 7 will turn on. But we want to turn on LED 5 and LED 3 only. Here, we have to go for the principle of "persistence of vision".

IMPORTANT NOTICE

All the circuits, published in this blog is only after testing and getting proper results in my private lab. When you try these circuits, you should check the supply voltage, polarity of components, presence of childrens nearby and shorts in the circuits. This website will not be responsible for any harm happened to you or your components caused by your carelessness.
