the voltage on the NTC decreases when the ambient temperature is high in the heat-sensitive circuit. T2 is the cut, T1 is the transmission. The relay contacts change position. When the envir... Read more
When it comes to drawing circuit diagrams, it’s damn hard to get a clear overview of all the benefits and functionalities different tools have to offer. However, in the end, everybody needs... Read more
This is a sort of sequel to the article ‘2 × single = 1 × dual’. In this case, two dual opamps are combined to make one new quad opamp. This allows many possible variations, and again it all... Read more
Hey there, In this section, I have made a nice conceptual circuit diagram that will help you to understand how ALU inside the computer works. Schematic Diagram: What is ALU? ALU is a combina... Read more
The sound generator shown here uses its built-in loudspeaker as a microphone when it is in the standby state. As soon as it detects a noise that exceeds an adjustable threshold level, it bec... Read more
