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 […]
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 […]
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 […]
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 […]
