A coupling capacitor is a crucial component in electronic circuits, primarily used to transmit an AC signal from one stage of a circuit to another while blocking DC components. Here’s a detailed overview of its construction, working, value selection and Applications: Construction of Capacitor: The construction of a coupling capacitor involves creating a device that […]
Among the various types of transistors, the Junction Field Effect Transistors in short JFETs holds a distinctive place due to its unique operational characteristics and versatile applications. What is a JFET? A Junction Field Effect Transistor (JFET) is a type of field-effect transistor (FET) that utilizes an electric field to control the flow of current. Unlike […]
Potentiometers are electrical component used to measure or adjust voltage or current, it usually consists of a rotary or sliding adjusting device, and three electrical contacts, one of which is connected to the power supply, the other is grounded, and the third can be moved on the adjusting device of the potentiometer, which can be […]
Creating an LED VU meter using the LM3915 involves designing a circuit that converts audio signals into visual LED bar displays. The LM3915 is an IC that drives 10 LEDs in a logarithmic scale, making it suitable for audio level meters. A VU meter, or Volume Unit meter, is an audio visualizer that uses a […]
This article describes a sensor-less BLDC motor driver circuit using 555 timer and DRV10866 motor driver IC, suitable for driving small 5V BLDC fans without position sensors. The rise in the use of brushless DC motors (BLDCs) is driven by their efficiency, durability, and precision. However, controlling these motors typically requires rotor position information to […]
Let’s see how to interface rain sensor with Arduino, a rain sensor, also known as a rain switch or rain detector, is a device used in various applications to detect the presence of rain and trigger a response. The basic principle behind a rain sensor involves detecting changes in conductivity or capacitance caused by the […]
