Light House Of World It’s a clock. Every electronic circuit needs a clock to beat to, (unless it’s something simple like turning on and off an LED,) just like your body needs a heart to beat too. The cool thing about the 555 is that you can easily change the clock’s frequency by switching out the capacitors and resistors

Very well explained though I'm from Mechanical Background.Can you please make a video to show how to control solenoid valves like fuel injectors in automobiles.

@fitulus 5 жыл бұрын

ECU of a car is a pwm ECU (not every car). That means it can send pwm signals to the solenoid that controls the valves. Each pwm signal from the ECU is a variable pulse, based on different data from the car sensors. for example data from maf sensor, map sensor, temperature etc.. Pwm can make a valve go half open or a little bit open or 1/4 go open because the voltage of that solenoid can have variable voltages. So if that solenoid is going open by 12V and going close by 0 volt. Then it will be half open by 6 volts. And 1/4 open by 3volts. and 1/8 open by 1.5 volts and so on and so on. This is only possible with pwm pulses. Annother example: solenoid makes a valve full open by 12 volts and closed by 0 volts. a pwm signal of 50 percent will create 6 volts in stead of 12. That's because pwm says "go to 12V and while going to 12V pwm says "go to 0V" but while going to 0V pwm says again "go to 12V" and this happens very fast lets say 1000x/sec. by this the solenoid never reaches the 12v and the 0 volt and thats what creates 6Volts. So a pwm pulse by 50 percent will create 6V.

Alternating current is already sinusoidal, you don't really need to make it that way. Adjusting its frequency, amplitude, etc. is really pretty fundamental, the real questions start when you're looking into what happens to a circuit when those things change.

PWM Its easy to understand in the synthesiser world because the pulse width actually does modulate usually with the aid of an LFO, however in this instance the pulse width is not actually modulating the time is always the same in every pulse however you could argue the LED is modulation on/off.

@johnwebb9176 3 жыл бұрын

Great video. I'm curious. Doesn't the potentiometer change the resistance of the circuit? Nothing really to do with the pulse width or hertz right ?

@bolibardo1514 3 жыл бұрын

Good simulation, still some questions because of my poor comprehension. (1) Does pulse width modulation appliy to only DC voltage? (2) Instead of chopping off the duration of voltage, why don't we provide a steady average voltage? This fluctuating voltage looks like a deliberate unsteady power ! (3) If we apply the PWM to an electrical motor, will not the motor's speed be a fluctuating one (instead of a steady speed)? (4) What is the objective of a pulse width modulation? Dimming a light? We can do the same dimming effect by using a low wattage lamp. (5) If the PWM voltage is applied to a solenoid, will it not induce reverse voltage because of changing flux? To me PWM is like breaking the leg of an athlete, to raise a special olympics champion. Thanks for the video.

5:50 How does the potentiometer/ microcontroller create more a efficient power supply? Could you briefly elaborate. Thank you for this video by the way. Some aspects of electronics videos are explained better than others. This video is one of the good ones as it is explained very slowly and clearly with excellent animation. Hopefully in the near future my successful circuits will reflect your effective teaching method. 😊👍

@forestdenizen6497 4 жыл бұрын

The pot is not in the power circuit. It is only being used to control the pulse width via an analog to digital conversion. You can control the pulse width any way you like, but a pot is easier for a demo than, for example, using a keypad to enter a number.

so basically can pulse width modulation be summed up in the following sentence: power switched on every x secs for a period of y secs where x is called the frequency and y is called the width, and is given as a percentage of the total frequency period?

I have a question that I hope you can help me with. I connected a pwm reversible speed controller to my trolling motor. This is supposed to be 100 max and 60 continuous amps. When I first tried it out. I noticed it got fairly hot in the enclosure I made for it so I decided to add a fan. I connected the fan to the 12 v power going in with an inline on off switch. When I tried it,the fan burned out almost immediately. Thinking I may have had a bad fan,I connected a new one with the same result. When I checked the power in with my multi meter,it was showing a very erratic reading. The volts were going up and down from 1 v up to 18 and in between. I even saw it jump to 36 volts. I'm using three 12 volt batteries in paralle. When i checked the voltage at the batteries,it was the same,just all over the place. For the heck of it. I tested the cigarette plug on the jump box that is one of the batteries connected in parallel and low and behold,it was showing the correct voltage which in my case was 13 volts on fully charged batteries. Looking inside the jump box. I notice that the cigarette plug was connected with a small circuit board. I assumed that the circuit board somehow regulated or should I say,normalized the voltage. I ended up running the fan on it's own circuit via the cig plug and it now works fine. The obstacle I'm trying to eliminate is,I also have a 12v steering unit for the trolling motor. I would like to connect the steering unit to the power in of the speed controller as to eliminate having to use another cord but I'm unable to with that type of voltage that it produces. Short of pulling that circuit board out of the jump box,would you possibly know what I can add to achieve this? Also,would you know why this pwm behaves in this manner? Thanks.
