Hello friends, I hope you all are doing great and having fun with your lives. Today, I am going to give you guys a detailed Introduction to PIC16F877a. It's the most commonly used PIC Microcontroller because of its operational flexibility, availability and low cost. You can buy this PIC Microcontroller from almost every online electronic shop for just $2 - $3.
If you are new to PIC Microcontroller then read this complete post carefully and ask your queries in the comments. You should also have a look at this video in which I have given an Introduction to PIC16F877a:

Hello everyone I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge on Introduction to TL494. It supports all of the functions that are necessary for the Pulse Width Modulation (PWM) control circuits. Power supply control is the basic purpose of the TL494 device. It has an output control circuit, a flipflop, dead time comparator, two different error amplifiers, 5V reference voltage, oscillator and a PWM comparator. TL 494 operates properly between the frequency of 1kHz to 300kHz.
The Dead Time Comparator (DTC) provides around 5% of dead time. Both of the error amplifiers display a common-mode voltage from -0.3V to (Vcc-2)V. If we provide a sawtooth wave at the CT terminal and terminate RT to the referenc ...
