What is a photo diode?

A photodiode is a type of light detector used to convert light into current or voltage depending on how the device works. Contains optical filters, integrated lenses and surfaces. These…

What is the voltage follower?

A voltage follower (also called unit gain amplifier, buffer amplifier and isolation amplifier) ​​is an op-amp circuit that has a voltage gain of 1. This means that the operational amplifier…

What is the lm386?

If you build a microcontroller sound sensor, you can install it on an LM386 based amplifier. It’s cheap, easily available and does not require too many external parts. A nice…

What is the function of lm339?

A dedicated voltage comparator will generally be faster than an operational amplifier for general use put into operation as a comparator. A dedicated voltage comparator can also contain additional functions…

What is an op amp and how does it work?

Well, the idea is to insert two electrical signals into the inputs, so the output changes accordingly. This takes the difference between the inputs and amplifications, then the operational amplifier…

What is the use of IC lm358?

The LM358 is a dual-core, dual-core, low-power operational amplifier, originally initiated by National Semiconductor. It is used in detection circuits. The LM358 abbreviation indicates an 8-pin integrated circuit that includes…

How does IR sensors work?

An infrared sensor is an electronic tool that is used to detect certain environmental characteristics by emitting and / or detecting infrared radiation. Infrared sensors can also measure the heat…

What is the function of laser diode?

A laser diode (LD), an injection laser diode (ILD) or a laser diode is a semiconductor device similar to a light emitting diode which is created at the junction of…

What is an IR photodiode?

An IR sensor is basically a device composed of a pair of IR LEDs and a photodiode collectively called optocouplers or optocouplers. The IR LED emits IR radiation, the reception…

How do you test a transistor?

Connect the marked terminal as positive, first to the collector and measure the resistance. Then take it to the transmitter. In both cases, the counter must deviate (indicate open circuit…

How do you test a diode?

Set up the multimeter to measure AC or DC voltage as needed. Turn the dial to the resistance mode (Ω). It may share a space on the dial with another…

Which way does a diode go?

Think of a diode as a one-way street for electricity. When the diode is in the feed direction, the diode allows circulation or current from the anode to the cathode…

What is the work of a diode?

A vacuum tube diode has two electrodes, a plate (anode) and a heated cathode. The most common function of a diode is to allow an electric current to pass in…
