Hey there,
I am new to this forum so if i place this in the wrong place tell me..
So I started few days ago on exploring the timer 555.. I watched the tutorials and so and then i moved an made a simple flashing led circuit ( a stable right? ). And moved on and made my own flashing circuit.. And as you can guess it didn't work.. it didn't work for 2 days. I tried a lot but nope.. But today i solved the problem. Well I didn't solve it but I found it maybe you guys know why.. The problem was in the DC Supply I was using some school thing DC supply very basic with only like 2/4/6/8/10/12 V DC/AC so when I connected it to the circuit the LED only stays ON and didn't flash.. Today I went to try it again and solve my problem and I had this 9V bat next to me and the dc supply was half meter far from me so i was kinda lazy and used the small 9V bat.. I am glad i was lazy..
I just shared this so maybe other people with the same problem.. try using a 9v bat. But what I don't understand why didn't it work with that power Supply? I also tried it afterwards with a good DC Supply and it worked.
But now back to my question... I just typed this all because I lost my hope and was opening a topic on forum for help.. but while opening the topic, i was just reading one last topic on solving the problem.. and it worked.
Now I have one question about the timing.. in lots of videos i saw this formule on the timing t = 1.1 x r1 x c1 and this should give you the exact time of the filling of the capicator/flashing led. But what I don't understand of the formule it doesn't indicate the Volt, because the volt is a very important thing in the timing right? the 1/3v and 2/3v.. so it would have a lot difference when t = 1.1 x 100k x 1uf and its 5v and when the volt is maybe 15v? Right.. Or did i not understand it good.. Or did i not do enough research yet?
i just feel like sharing this all with you, because im pretty in joy after like 2/3days sturggling on this timer 555.. I am glad it was not a fault from the circuit but just the DC supply it was really driving me mad but patience wins
