A zero crossing detector circuit is a simple electronic circuit used to detect the instant when the AC (alternating current) signal crosses the zero voltage point. It is commonly used in various applications such as in power control circuits, phase control circuits, motor control circuits, and in instrumentation. Zero Crossing Detector Circuit Here’s a basic […]

Current Switching Circuit using Arduino
Hello friends, Current Switching Circuit using Arduino? Do you know how to switch between two power supplies or current sources using Arduino and Relays? Welcome to another interesting article, suppose you want to operate a device that can be operated based on the room temperature or a temperature inside the device, let’s understand this with […]
Automatic Night Lamp Circuit Diagram by LDR & LM358 OPAMP
This article explains automatic night lamp circuit using a high power LEDs circuit which automatically turns the LEDs ON at night and OFF when it is daytime. The sensing part which is being used for detecting the light is Light Dependent Resistor (LDR). The resistance of LDR depends on the light incident on it. Greater […]

LM380 Audio Power Amplifier Circuit And it’s Working
The LM380 is an audio power amplifier for consumer application. Its internal gain is fixed to 14dB in order to keep the system cost minimum. A unique input stage allows inputs to be referenced with the ground. The output gets automatically self-centered to one half the supply voltage. The output amplifier is short circuit proof […]
Triangle Wave Generator using OPAMP
In this article, we will discuss how we can make a triangle wave generator using opamp. So, let’s start discussing how to make a triangle wave generator. A triangle wave is consisting of a constantly rising and falling slope. An opamp integrator gives a triangle wave. If you are an electronics student then you might […]
