Something like this perhaps http://everycircuit.com/circuit/6604200091058176

Mr @2cent likes to messup circuits. I just changed the simspeed to 1ms/s the circuit itself is untouched. http://everycircuit.com/circuit/6040198004867072

@mizra1976 ... hope you enjoyed seeing the variation without the diodes...Notice that the simspeed was also shown as altered to 1s there to show that we need to keep an eye on that aspect.

@hurz ... he wanted a 555 dimmer (see his title) ... mine does that at any sim speed. Yours does not act as a dimmer at any sim speed, and yours flashes... which was not asked for... and it wouldn't even be seen to flash by the human eye at that setting of yours. Also... yours does not work at all once the pot wiper is moved .. lol

Mr 2cent, the main issue without knowing what @mirza1976 really is looking for is the simspeed! Step by step. What you did is a total mess, look were you have connected the ground at the pot. You have no idea what @mizra1976 really want, but you mess around like a baby. ridiculous! Keep the circuits as is and tune the simspeed to something which makes sense, everything else is messing. after simspeed is somewere it makes sense, go again into discussion with @mizra1976.

@2cent, also you probably dont understand what PWM is all about, for you as simple as possible explained, its flashing which the human eye can not see in different ratios. Your circuit does NOTHING at any simspeed. http://everycircuit.com/circuit/5138899151355904 Your circuit is absolut nonsens. Funny how you baby tries to attack other users but you are completly loost and know nothing about electronic simulation.

@mirza1976, its hard to understand the simspeed parameter. Play around with the clock symbol and its values. For most beginners already the unit looks strange "s/s" seconds per seconds. It says how much real time the simulator runs within a second of simulation time. The number of time steps the simulator can calculate within a second is limited. So a circuit with high frequencies has to run very slow and can not run close to "real time". Again, its difficult to understand and difficult to explain 😁

@hurz ... you are talking total crap in the hope that some users will fall to your deceiving nonsense.. I am well aware of simulation speeds and PWM (plenty articles of mine here throughout the last 2 years). Utter lying nonsense as usual from you in an effort to win every argument regardless of sense.

Tell us more about the PWM in your bullshit circuit, PLEASE we are all listening http://everycircuit.com/circuit/5138899151355904

The mirza1976 effort here is not a good effort regarding PWM, that is by the way. Your pathetic simple sim alteration only makes that worse (as seen). It shows that you do not understand the detail of PWM (or are prepared to hoax in an effort to divert). Feel free to look up PWM on the net or in my earlier presentations. My effort here is based around a 50% pulse width...yours has no structure and does not account for unwanted frequency alterations....proof of the pudding as seen... no more stupid divertions and lies will help you here...Mine works ...yours is seen not to.

Yours is bullshit, it does not even oscillates. You must be blind and/or an complete idiot. And for this bullshit all your attacks, go and shot yourself.

@mirza1976, your circuit is fine, only the simspeed must be changed see my example circuit and for the diodes you need one more volt in supply from 5 to 6V. Nothing else to change, Forget the @2ctiby bullshit. Again your circuit is fine as it is!

If I had wanted an astable 555 for oscillation, then I would have produced one...but here I have presented a dimmer based on one.... it is obviously beyond you... you are incapable of learning from lower beings, ie from everyone else in the world... even when the result is here staring at you.... the 555 is not the only thing that can be dim around here.

Listen to the crap you are talking?

Mine is seen here dimming as requested ... yours here does not show dimming ... PWM dimming is a different option, which is not enacted here properly by your futile adjustment ... end of story.

Oohhh Mr Messy, my is working as PWM and yours is still BULLSHIT. So have a banana 🍌 and go away idiot.

@mirza1976 ... To make a simple dimmer, the 555 is not needed at all. Just a pot to the battery is all that is needed (rather like my effort in effect, though be careful not to have too low a minimum wiper resistance). If you are wanting a more efficient dimmer control, then PWM is what you may wish to research. If you do that, then aim to keep the frequency static ... notice that with your wiper movement the shown scope frequency alters and so offsets the pulse width alterations (as with the similar hurz model) ... That should be avoided unless it is part of your design.... good luck.

@mirza1976, have fun with the 555 as 20 Ohm resistor, LOL
