Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give you an Introduction to LM741. It belongs to the series of general purpose amplifiers. It supports larger range of input voltages. LM741 provides high gain and short circuit protection as well. Its pins configuration is very similar to UA709 and there is no need of frequency compression in LM 741.
LM741 can be used as a comparator in order to determine the levels of applied input voltages i.e. either smaller or larger input voltages are applied at its input terminal. LM741 is an op-amp IC having 8 different pins, which will be explained later in this tutorial. LM-741 has a very wide range of applications e.g. function generator, comparator, DC amplifie ...

Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at a detailed Introduction to TCS3200. TCS3200 is a color-detecting sensor, it consists of TAOS TCS3200 RGB sensor chip and four white LEDs. It is used to detect visible color in a measurable range. This sensor has an array of a photodetector diode, some diodes are equipped with different color filters i.e. red, blue or green color and some diodes do not have any filter.
TCS3200 has different applications such as test strip reading, sorting by color and ambient light sensing. In today's post, we will have a look at its working, protocol, pinout, specification, etc. I will also share some links where I have interfaced it with other microcontrollers. If you have any questions about it ask in the c ...
Hey Everyone! Hope you are getting along with life pretty well. I always strive to keep your technical appetite filled with the recent and valuable development in engineering and technology. Today, I'll unravel the detailed Introduction to USB.
The USB stands for Universal Serial Bus which is an industry standard mainly developed for laying out the communication between a computer and peripheral devices. The first USB was developed in 1996 by the collaborative effort of seven companies - DEC, Microsoft, Compaq, Nortel, IBM, Intel, and NEC
The USB device not only helps in establishing a flawless communication but also assists to power up the connected peripheral devices, setting you free from the parallel ports and the external power charg ...
Hello Everyone! Happy to see you around. Thank you for clicking this read. In this post today, I’ll document the Introduction to MJE13007.
MJE13007 is an NPN bipolar junction transistor that is a semiconductor device made of silicon material. This chip is mainly used for amplification and switching purposes. The collector-base voltage is 700V while the collector-emitter voltage is 400V. The power dissipation at temp 25C is 80W. This means 80W is released during the working of this device. This device can support load up to 8A because the current at the collector side is 8A.
I suggest you read this entire post till the end as I’ll include the complete Introduction to MJE13007 covering datasheet, pinout, working principle, power ratings, applications, and physical dimensions.
Let’s ...
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 ...
Hello readers, I hope you are all doing great. In this tutorial, we are going to discuss the OTA web updater on the ESP32.
We already covered the fundamentals of OTA programming in ESP32, in our previous tutorial where we used the Arduino IDE to upload OTA code into the ESP32 module using the network port.
In the OTA web updater, you need to create a web server page for OTA programming.
