Hacks of Electronics
In this blog you can find opamp tutorial and circuits like differentiator integrator, summing amplifier and many more circuit. Operational amplifier basics detailed explanation and working of each circuit.
An operational amplifier is a DC-coupled high-gain electronic voltage amplifier amplifier that has high gain, differential input, high input resistance, and low output resistance.
There are mainly two types of opams amplifiers inverting amplifiers and others one is non inverting amplifier.
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 […]
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 […]
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 […]
In this project, we will use the MQ2 Gas sensor circuit to detect Methane, Butane, LPG, Smoke which is released into the environment at the time of the gas leak. MQ2 Gas sensor circuit diagram is as shown in the figure. MQ2 gas sensor can sense butane, LPG, Smoke, Alcohol, Propane, Hydrogen, Methane and Carbon […]
A voltage comparator is a circuit which compares the voltages at its input terminals and switches the output to either high or low depending upon which input was high. making a voltage comparator using transistors and other components is quite difficult and makes no sense because we have OPAMPs. We can use 741, LM311, LM324, […]
Voltage to current converter is mostly used to transmit signals over a long distance to a control circuit. The most important reason behind it is that while traveling a long distance due to the internal resistance of the wire the voltage gets reduces. if there is a very small signal then it may get lost.
