A boost converter circuit is a DC-DC power converter that steps up voltage from its input to its output while stepping down current. It’s widely used in applications where a higher output voltage is required from a lower input voltage, such as in battery-operated devices. One of the simplest ways to design a boost converter […]
Let’s get started with types of oscillators, how they work? and what are the common applications of oscillators. What is Oscillator? Oscillators are electronic circuits that generate periodic waveforms from a DC source without any external input signal. They are widely used in various applications, including clocks, radios, computers, and signal processing. Working of Oscillator: […]
Let’s designing a PIR motion sensor circuit that uses a Passive Infrared (PIR) sensor to control a buzzer through a 555 timer for motion detection applications. Here’s a step-by-step guide to creating this circuit: Components Needed: PIR sensor 555 timer IC Buzzer Resistors (various shown below) Capacitors (various shown below) NPN transistor (e.g., 2N2222 or […]
Let’s understand in detail what are the difference between Microprocessor and Microcontroller. Microprocessors and microcontrollers are both essential components in the field of electronics and computing, but they serve different purposes and have distinct architectures and applications. Here are the key differences between them: What is Microprocessor? A microprocessor is a central processing unit (CPU) […]
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 explore T flip flop truth table and working of its circuit with applications. A T flip-flop, also known as a toggle flip-flop, is a basic digital circuit element that has two stable states and can change state (toggle) based on a triggering input. T Flip Flop Circuit Diagram: Here’s the circuit diagram for a […]
