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.
A Schmitt Trigger circuit is a comparator circuit with some modifications. As compared to a normal comparator circuit the Schmitt trigger circuit has a hysteresis curve. This means that it has two threshold voltages an upper threshold and a lower threshold voltage. In Schmitt trigger hysteresis is created by applying positive feedback to the non-inverting input […]
Voltage controlled oscillator circuit is an electronic oscillator circuit whose output frequency is controlled by an input voltage source. By varying the input voltage, we can change the output frequency. A voltage controlled oscillator can produce frequencies ranging from few Hertz to tens of Gigahertz. Voltage to frequency converters is used in frequency modulation FM […]
LM317 is an adjustable voltage regulator IC. In this project, we will be making a 1.25V to 37V LM317 adjustable voltage regulator circuit. This IC can provide an output current up to 1Amp. It’s a three-terminal positive voltage regulator IC. This voltage regulator requires only two external resistors to set the supply voltage. It has […]
In this project, we will see how to make a triangle wave generator using the 555 timer IC. 555 timer is a very versatile delay and square wave generator IC. It one of the most used ic in electronics projects. You might have used or seen a waveform generator. It is an instrument that can […]
IC 7490 is Asynchronous mod-10 Counter IC. In this article, we are going to study IC 7490 Decade Counter Circuit. IC 7490 is also known as BCD Counter, Decade Counter, and mod-10. These names are given based on the Functionality and Working Principle of IC 7490. Counter Designing using 7490 IC: In the discussion of Counter ICs, some basic […]
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 […]
