00:04Welcome! In this video we will build a circuit that represents a meter.
00:11water level with three levels, the lowest level being 1, the middle level being 2
00:16and the
00:16The one higher than that 3 is powered by a 12-volt source and operates on the basis of
00:22From the base of three 12-volt transistors, we take a cable that goes to the bottom of the tank and from each
00:28One of the transistor bases goes to a wire that goes to the different levels, so when the
00:34When the water reaches a certain level, it will act as a bridge between the voltage cable and the cable.
00:40The transistor base, for example, in the simulation, now appears as if the level were at its maximum.
00:48The LED turns green if the level drops; the LED turns yellow if the level drops.
00:54If it keeps going down, only the red LED would be lit, and this gate would also turn on a booster.
01:02which would represent telling the user they need to turn on the pump, and if we look here, it has the
01:10The voltage and the booster sounds when it's at its lowest level. Okay, if you think it's useful to you, no.
