Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give you a detailed Introduction to PC817. PC-817 is also known as an optocoupler / optoisolator. It consists of Infrared Emitting Diode (IRED). This IRED is coupled to a photo transistor optically and not electrically. It is closed in a four (4) pin package. This package is usually available in two different forms. The first one is wide lead (Pb) spacing option and the second one is SMT gullwing lead form option.
PC 817 has an internal LED and a photo transistor. The photo transistor's base becomes activate when LED throws light on it. The output obtained can be divided into two formats either common emitter or common collector. But the configuration is ...
Major League Hacking, also known by its official acronym MLH, organizes student hackathons. MLH was established in 2013 by Mike Swift, who previously worked for SendGrid and Jonathan Gottfried, who formerly worked for Twilio. The two are former developer evangelists.
All hackers at MLH events have, for the last two years, been getting a special voucher code from Domain.com. With this coupon, and several other deals, the students at each event can register a free domain (.com, .net or even .org), get better prices on hosting.
Additionally, the most innovative domain name at each MLH event gets rewarded with a bag full of great hacker gear.
What exactly is MLH?
At first, MLH was intended to facilitate North American student-run university hackathon ...
Hello everyone! I hope you all will be fine and having fun. Today, I am going to give you a detailed Introduction to MAX232. It is an Integrated Circuit(IC) embedded in a single chip and acts as a voltage-level converter. MAX 232 is capable of converting 5V TTL Logic level to TIA/EIA-232-F level and can take up to +-30V input. It is normally used for the communication between microcontroller and Laptop/PC.We can use MAX-232 to convert Transistor Transistor Logic (TTL) voltage level to RS232 and vice versa. RS232 is the method of transferring data using serial communication. MAX 232 is a dual receiver or driver having a capacitive voltage generator to supply RS232 voltage levels from a single supply of 5V. Each receiver converts RS232 inputs to 5V either Transistor Transistor Logic (TTL) ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to 2N3906. It is most common Positive Negative Positive (PNP) Bipolar Junction Transistor (BJT) available in the market now a days.
2N 3906 is specially designed for low power amplification purposes as well as for switching purposes. 2N 3906 is designed for low current, power and for medium voltages. It is capable of operating at moderately high speeds. The range of its collector current is form 10uA to 100mA. Further detail about 2N-3906 will be given later in this tutorial.

Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to explain you about Introduction to TL431. TL 431 are programmable shunt regulator diodes having three terminals. Its a low temperature coefficient diode and can be programmed from reference voltage (Vref) up to 36V when it is attached to 2 external resistors.
TL 431 has an impedance of 0.22 ohms and has a current range from 1mA to 100mA. In several different applications zener diodes can be replaced with TL 431 diode due to its efficiency. These applications include power supplies, Operational Amplifier (Op-amp) circuitry and digital voltmeters. TL-431 can either be used as positive or as negative voltage reference because it operates as shunt regulator. T ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to 1N4007. It is a PN junction diode. Diodes can be made by combining two different types of semiconductor e.g. P and N. PN junction is a junction formed between P and N types of semiconductors. You guys should also have a look at Introduction to 1N4148.
1N 4007 belongs to the series of 1NXXXX devices. Its an American standard numbering system standard used for semiconductor devices. This standard has been adopted globally now. In 1N 4007 the first part 1N indicates single junction semiconductor. 1N indicates 1 junction whereas N indicates the semiconductor diode. 4007 is the specific number to indicate the particular ...
Essay writing for the most part request that you exhibit that you have drenched yourself in the course material and that you've done some reasoning all alone; questions not treated finally in class regularly fill in as assignments. Luckily, in the event that you've invested the energy into becoming more acquainted with the material, at that point you've more likely than not started suspecting autonomously. In reacting to assignments, remember the accompanying guidance.
Beware of straying. Particularly in the draft stage, "talk" and "examination" can lead you starting with one characteristically fascinating issue then onto the next, at that point another, and after that ... You may end up following a garden of forking ways and lose your direction. ...
Hello everyone, I hope you all are doing great. In today's tutorial, we are gonna have a look at How to Improve Assignment Writing Skills in College Life. Not every person adores composing, and I'm not much persuaded that individuals should love composing. It's diligent work. I have an adoration loathe association with composing that has been developed more than quite a long while. I've heard understudies wail over the way that they need to write in their classes, as though composition were something to be dreaded and taken care of like a hot poker. I address these worries each day in the written work classes I educate, and in my own particular head, as I endeavor to sort words on a PC screen.
Composing is hard, and nobody ought to ever attempt to ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to LM358. LM-358 consists of two independent high gain frequency compensated operational amplifier. They are specially designed to operate from a single supply or split supplies over a wide range of voltages.
LM-358 have lot of amazing features associated with them. These features include wide supply ranges, low supply current drain, independent of supply voltage, wide unity gain bandwidth, ground includes I common mode input voltage range, low input bias, open loop differential voltage gain, internally frequency compensation etc. LM 358 has a lot real life applications e.g. Operational Amplifier (Op-amp) circuits, tr ...
