PWM 2 for BEGINNERS, pulse width modulation, Arduino, WEMOS, Servo.

In the second episode about PWM, i.e. pulse width modulation, I will show examples of GENERATING such signals using MICROCONTROLLERS - there will be simple PROGRAMS, I will also show how to control the SERVO - how to generate a signal and how this signal translates into the position of the servo arm. In a simple way, for BEGINNERS.
I will show it in the SIMULATOR and in PRACTICE - there will be a free simulator, but also NODEMCU, WEMOS, SERVO, DIODE, OSCILLOSCOPE.
Since I am not a programmer - my code may contain errors, although it works, it is intended to show in the EASIEST WAY possible how to generate signals, so I only used BASIC commands.
Part one:
• Podstawy PWM - modulac...
I invite you to watch!
0:00 Introduction
0:18 Diode - change of fill factor - example in the simulator, basics of PWM generation - digitalWrite() and delay() - disadvantages of this solution
3:02 Using analogWrite()
4:18 Servo arm control - example in the simulator
7:18 NodeMCU - diode brightness control - practical example, Arduino IDE, oscillograms
9:25 Servo control - practical example - NodeMCU without using a library
10:27 using the library to control a servo using WeMOS D1 mini
11:15 Servo control using the generator from the first part - calculations
11:56 PWM generator and servo - how it works in practice.
