Let’s Explorer Carbon Composition Resistor symbol, construction, working, types, value reading, advantages, disadvantages, and applications explained in the clearest way. Carbon composition resistors were once the most common type of resistors used in electronic circuits. Though largely replaced by more modern resistor types today, they still hold importance in high-energy pulse and vintage circuit applications. […]
Resistors are fundamental electronic components that limit, regulate, or set the flow of electric current in a circuit. While they may appear simple, there are different types of resistors designed for specific purposes and operating environments. Now you know the basics of resistance and its role in circuits. Let’s dive deeper into the all the […]
Constant Current Diode (CCD) (also known as Current Regulator Diodes, or simply CRDs) are unique semiconductor devices designed to maintain a constant current over a wide range of voltages. They are extremely useful in circuits where a stable and predictable current is crucial, regardless of voltage variations. In this article, we will cover the Symbol, […]
An Astable Multivibrator is an essential oscillator circuit in electronics, used to generate continuous square wave signals without any external triggering. It is called “astable” because it has no stable state — both transistors in the circuit keep switching ON and OFF alternately, producing a continuous flip-flop output. In this article, we will explore a […]
Creating a wireless remote-control car using 433MHz RF modules is a classic electronics project. This guide explores a fully functional DIY 433MHz RF Remote Control Car Circuit using the HT12E/HT12D encoder-decoder pair, STX882/SRX882 RF modules, L293D motor driver, and BC557C transistors. We’ll also delve deep into how the transistors and diodes manage motor control and […]
Explore Universal NAND Gate from its truth table to its IC pin diagram, delve into transistor-based logic circuit construction and working, and discuss the advantages, disadvantages, and various applications of the NAND gate. Just as the NOR gate combines the OR and NOT functions to provide an inverted output when all inputs are low, the […]
