Hacks of Electronics
Here are the basic electronics tutorial circuits for beginners. You can find here tutorials on operational amplifiers (opamp), transistor, MOSFETs, 555 timer IC, audio amplifiers and many more.
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 […]
In this post, we will see FM Transmitter Circuit Diagram. FM transmitter broadcasts the signal from any audio device to a standard FM radio. This transmitter is open when the signal has to be reached to some long distance.FM means Frequency Modulation. It carries the audio signal (20 – 20kHz), then it is being loaded […]
Here we will see the LED flasher circuit diagram and how it works. Flashlights are used in vehicles to pass left-right signals. At many places where two people cannot talk this LED flasher can be useful. We can give signals by flashing lights of different colors. You are familiar with the Bike turn signals indicators. […]
Scaling of MOSFET means, the Reduction of scales from something, Hey! Friends let us first understand what is the basic idea behind the scaling of MOSFET? Scaling is one of the best ways to increase the performance of the Metal Oxide Semiconductor Field Effect Transistors (MOSFET). In scaling we reduced some critical parameters of the […]
Let’s see how to interface Arduino with temperature sensor. LM35 is a three-terminal temperature sensing device. It is used to measure temperature in the range of -55°C to 150°C. It is a three-terminal device that produces an analog voltage proportional to the temperature of its surroundings. We can convert the analog output into digital using […]
In this article you will see Arduino LCD Program with Interfacing Diagram. Liquid Crystal Display (LCD) is now being used in every electronics field either it is analog or digital. To learn how LCD works with Arduino, one should know the basics of LCD. Commonly used LCD has 8 bits. Standard 16×2 LCD Display: There […]
