what is the ampear of the dc power source ? how much ampear dc adapter should i use ???? i know the voltage but about the current
If I have to control the power to a resistance, what is the difference between a pwm+mosfet and potentiometer+mosfet? Isn't easier to use a potentiometer+mosfet?
what happens if I don't put the two 1kOhm resistences to the Gate of the Mosfet?
Hi, I just built this circuit. I have a basic question: I’m using a 12V 3Ah battery as power source and my MOSFET and 555 IC are heating up a lot!! Am I doing something wrong? Is it that the battery pack has a high current output?
Thank you for this video! Fantastic explanation. I'm trying to do something similar but using a joystick to control a proportional solenoid for a hydraulic setup.
I have one question. What is a benefit of using 555 if we can already control motor just with just potentiometer and transistor? Of course there should be a benefit of using this circuit. But what is it.?
My circuit doesn't work 😢
This was my load controller project with lm311 current limiting
Thank you for this. Great explanation of how a 555 timer works in a pmw motor control circuit.
为什么我把12V电源接到电路板输出端时，会瞬间冒烟燃烧？
Why not just connect the potentiometer to the motor to adjust the motor speed? What a difference this complex circuit makes?
So, motor speed controler is like buck converter right?
Why is there no capacitor parallel to the motor to smooth out the PWM?
And I will give you a chewy cookie if you don’t stop this series ok😂😂😂😂😂😂🎉😅
I am creating a ne555p circuit whith almost every component pnp and npn transistor diode ne555p wires resistor capacitor
WELL EXPLAINED LIKE EXPLAINING TO A 6YO! I got a question
13:05 Where you calculate the charge time of the capacitor, where does the number 0.693 come from? Thanks in advance
I didn't get the PCB Gerber File
This is rated five wow's. Perfect explanation of the 555 TIMER AND CIRCUIT. Awesome video. Great teacher.
😅😅😅😅😅well ingormeti0n.Good show more 😅😅
can you tell me the name of the add-on that you are using to get the components library?
This circuit work only with DC motors or it works with AC motors too?
Your bread board is so clean. I'm going to start working to keep my work as tidy. I like how all your grounds are on one side and all your hots are on the other, makes it very easy to follow.
This is what YouTube is all about. Thank you so much for making these!
Is there a difference between the LM555CN and the NE555 timer? Does it work the same?
Does the AVG voltage drop with frequency or is it the time on to time off ratio? The AVG is the integration over time so the area of a fifty percent duty cycle is still the same no matter what frequency ?
Excellent video, how do know all these things about building a circuits? Is there a good book which explains building complicated circuit projects?
MashAllah
Variable resistance?‽
lemme tell you good this video is and generally this channel: I got mad when I saw, that I was not subscribing… I clicked it like a Blitz!
Can i put te motor in reverse with these circuit?
How we know how much it will be robust and then can yoi control this through an APP
Hello, do you have a drawing of the board in PDF? Thanks
