Many times it happens that if our circuit is small enough then the power source is also needed of small value. And many times we need to pack our circuit in a small box. In these circumstances, we can neither…
As you saw in our previous circuit that was made on TL431 and was used to tell the level of a charged battery. Today’s circuit also does something similar, but it has two LED lights. We can put this circuit…
Today’s circuit is very simple and quite useful. This circuit can be easily made using fewer easily available components. The work of this circuit is that as soon as our battery reaches its final voltage of 14.2 the red LED…
Many times this happens that you charge your phone with some other brands mobile charger and the charging goes slow. That means the charger supports the same brand’s charger only. Now have you ever thought of this feature? How this…
