For buildings that are big and tall where the water tanks are kept way up high over the terrace, keeping an eye on the water levels all the time by […]
How to Make a 220V, 25 Amp Heater Controller Circuit
Here, I will explain how to construct a 220V operated basic heater controller circuit at a current rate of 25 amps employing a standard triac-based dimmer switch circuit in this post. […]
Make Solar Voltage Battery Charger Controller using LM338 IC
Here we have a simple solar battery charger circuit using LM338 which is a voltage regulator IC but we use it for charging. So now, let us understand how this […]
ULN2003 Water Level Controller Circuit
The ULN2003 is a chip which contains seven separate sections, each made up of special transistors called Darlington pairs. These pairs are designed to manage moderate amounts of electrical current, […]
Water Level Controller Circuit Using NOT Gates IC 4049
You can make a basic device to stop your water tank from overflowing using just one IC 4049 chip. This device, not only prevents overflow but also shows you the […]
