In this article, you will learn how to design a 12V 5A SMPS circuit that converts 230VAC to regulated 12V DC using the TOP227YN in a flyback configuration. Switched Mode Power Supplies (SMPS) are widely used for high-efficiency AC-to-DC conversion. The flyback topology is especially suitable for low- to medium-power isolated supplies. The TOP227YN is […]
Every electronics project reaches a point where the circuit works, the code runs, and the breadboard prototype does what it is supposed to do. The next step is putting it into something that protects the board, manages heat, and looks like an actual product rather than a tangle of wires zip-tied to a plastic box. […]
In this project, we will make a CD4047 Inverter Circuit, and we will also discuss why this type of inverter is not a good or reliable solution for real-world applications. An inverter is an electronic device that converts DC voltage into AC voltage. Inverters play a very important role in power backup systems, especially in […]
Temperature monitoring is a fundamental requirement in modern electronic systems, ranging from consumer appliances and industrial equipment to power electronics and laboratory instruments. An LED temperature display circuit using LM3915 and a thermistor offers a simple, reliable, and visually intuitive way to indicate temperature variations without the complexity of microcontrollers or digital displays. This circuit […]
If you want a compact, low-cost home media server that streams movies, TV shows, music, and photos to TVs, phones, and smart home devices, the Raspberry Pi 5 has become one of the best value-for-money platforms available. With its improved CPU performance, faster I/O capabilities, and support for NVMe storage, it stands out as a […]
A Motion Sensor Light is an automatic lighting system that turns ON when it detects movement in its range and switches OFF after a certain period of inactivity. This system is widely used for energy conservation, security, and convenience. The circuit described here uses a PIR (Passive Infrared) sensor, a BC547 transistor, a relay, and […]
