This article explains an automatic night lamp circuit diagram using LDR and LM358 OPAMP 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 a Light Dependent Resistor (LDR). The resistance of LDR depends on the light incident on […]

Stereo Amplifier Circuit 20W + 20W
If you are looking for a first-class 40-watt music stereo amplifier, then look no further. High output efficiency, negligible hum, low harmonic distortion, clarity of the output sound, compact (modular) size, and low cost are some of the key features of this fully solid-state integrated Hi-Fi stereo amplifier which is capable of delivering an output […]
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 consists of a constantly rising and falling slope. An opamp integrator gives a triangle wave. If you are an electronics student then you might […]
Automatic street light circuit
Have you thought about who turns on and off those street lights on the road? Turning on and off those street lights may be a boring task. We can make this process automatic by a simple automatic street light circuit. Also, you can automate your home lighting, lights in the garden, and other outside places […]
