Great video. You explain things very well. Ignore I need to stop the video and rewind. I do like your detailed explanation as I learn more, I appreciate the level of detail you bring to your videos.

OMG!!!! thank you thank you thank you!!!!! I've been working on this one mode for probably a week and could not get it to work. I didn't have a stupid 0.01uf ceramic capacitor and thought maybe that was the problem. I watched countless videos. They all start out with explaining how the chip and circuit work and I had seen them so much I could recite that part by memory.

I was getting frustrated I couldnt get it to work. I used a 10uf 25v capacitor instead of 50v. Finally I seen some chips I ordered but have never used them. They look just like the 555 timer. So I read the package and I was using a lm 386 . I changed the chip to the correct 555 and it works. Great learning video. Now I am going to switch capacitors and resistors to experiment and learn about this 555 chip.

So how do I fix it so when I hold the switch the output doesn't continue be high. I'm trying to get about 2 millisecond signal but it's affected by how fast I can press.

Thanks, Good stuff!

[@celtichongy]

Good job.

When I meter the capacitor after pressing the button the capacitor builds volts. I put a 1000uf in so it would take longer. The capacitor builds to about 3.3 volts then the led cuts off. When the led is off and I meter the capacitor it's 0 volts.

Which resistor do I need to change to make the duration of the LED being lit longer? Thanks, the video is very clear and concise.

[@Kevinthomaswatson]

Is there a circuit like this that would make the led go on and off three times then stop until the voltage is re-applied? Thanks.

How do I get it to go off even if I hold the button down cheers
