    Should we know the max voltage that the led can take? So we can figure out how strong of a resistor you need to use? If you do, then what is the average max voltage it can take?

    How about show us how to build a fucking robot

    College professors make mistakes with their wordage too, yknow.

    Just a quick tip, in advanced circuits never put your electronic voltmeter like that directly. Because voltmeter is electrical and has self resistance in it, it is putting some extra current through the circuit, which may damage small components very easily.

    This is a great demonstration and just awesome. I took vocational course on electronics and whatever they taught me, I didn't understand as much as was explained here. Thanks for turning on the light for me.

    I just wanna say. I've been taking notes on your video series. I. LOVE. Robotics now. Thank you! I was so excited to come home and learn more. I need some equipment to play around with =/

    @colorsoluble I do agree with u, it's pretty easy to criticise but really hard to do something productive. As far as mistakes, they r made by even NASA and Russian space agencies etc etc where thousands of extraordinary intelligent, best qualified and genius scientists, engineers and technologists are present.

    @colorsoluble I'am agree colorsoluble.

    When you measured the end of the black line after the led light, I thought it was because you were basically measuring nothing. since it is like your measuring the minus part of the battery twice.

    I appreciate the information thenewboston. Just a quick question: Isn't it more practical to use a smaller battery if possible? I've been watching your videos and understand why you're using a 9v battery (easier to work with).

    My thoughts are that the battery output will be the same regardless to how many resistors are connected, so basically the more resistors you use the more power wasted. What happens to the additional electricity as it flows through the resistor, is it lost?

    @asdzxc447 the voltage befor the resistor is 8.3, after the resister is 2.8, do the math.

    your videos are just amazing, it is nice from you to spend time in making them .. please dont stop ..

    he is not very clear but on the part you buy it will tell you how much voltage it needs

    google ohms law

    and by using that formula you will find out how many ohm resistor you will need to get the nine volt battery down to the amount of volts the part needs

    very nice i been watching all of them and i build a pc already i got a pcchips motherboard 6 gb ram and 1 tb hdd with xp and it is was it also has a ati graphics card that i put in with 2 cd/dvd pkayer/burners
