          We had already seen the internal circuit of 2*2*2 LED cube in the last blog. Here, we will make some modifications in the circuit to turn on LED 2 only.

          If the circuit is done as given above, LED 2 will turn on. Positive terminal of 5V cell is connected to the anode terminals of LED 1, LED 2, LED 3 and LED 4 through a current limiting resistor of 1K. Negative terminal of 5V cell is connected to the cathode terminals of LED 2 and LED 6. From these two connections, we can conclude that the only LED which will get both positive and negative voltages is LED 2. This will turn on LED 2.

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.
