C:
#include <TimerOne.h>
const int pin1 = 9; // Timer1 uses pin 9 and 10 for most Arduino boards
const int pin2 = 10;
const long frequency = 50; // 50Hz
const long period = 1000000 / frequency; // in microseconds
const long halfPeriod = period / 2;
const long pulseWidth = halfPeriod - 2; // Deducting 2 microseconds for the deadtime
void setup() {
pinMode(pin1, OUTPUT);
pinMode(pin2, OUTPUT);
// Set up Timer1
Timer1.initialize(period);
// Set the PWM period for each pin
Timer1.pwm(pin1, 512); // 50% duty cycle
Timer1.setPwmDuty(pin2, 512); // Set the duty but do not start it yet
// We create a manual interrupt to precisely control the phase difference
Timer1.attachInterrupt(togglePins);
}
void togglePins() {
static bool toggleState = false;
if(toggleState) {
digitalWrite(pin1, HIGH);

} void loop() {
// No logic in loop. The Timer1 library and ISR handle the toggling.

There are too many specific ones to make listing them worthwhile IMO, but knowing the essential operation of certain families of ICs would be useful, for example CMOS logic, op-amps, voltage regulators etc.
Have you read through the Resources section of this site?
Hello,
Here is a link to the resources page:

Seriously??.
You are going to starve yourself of help very soon.
Many contributors to this forum have spent a lot of time helping you. I prefer calling it ‘baby sitting’.
From all your threads, you haven’t learned anything. You haven’t read the links. You haven’t done the calculations that were shown. You haven’t even tried some of the suggestions.
Your internet connection..
You can post links ( in other posts) just fine.
Are you too damn lazy to Google??. Or an 8 year old?.

I have learned a lot to be fair, like how to make H-bridge with two half bridges IR2110 (to make a funtional inverter) and that's because they use NPN MOSFETS which switch faster than PNP and I learned about bootstrapping, I've learned to use new programs LTSpice and KiCAD and how to load in new libraries such as the zzz series. and have learned about how to model transformers to reflect reallistic out put. I learned about laser printers and photopaper for the toner transfer with the iron method at 130 degrees, and have learned a few other things too. I do read the material that you guys provide i'm sorry if it appears that i do not. I appreciate that you dont like to "baby-sit" so from now I will keep my activity to a minimum
