nice vid. I thought i was measuring my pots wrong or something, but this confirmed i was doing it right. My problem is i have 5M ohm pots, and want to measure the resistance at certain points on it. when i try to measure, its always a number that wont stay stable, for example, it starts reading 1000ohms and climbs to 100 000 ohms, and then starts falling back down again. simple resistors like 1k measure fine. is there something wrong with my meter, or am i just going nuts?

I would look at my meter and verify it is capable of 5M ohms, and then verify that the meter is working correctly by checking resistance on a known good component.

great instructional format.

Thank you very much for your feedback!

and check the battery in your meter!

what can i do with a bridge rectifier, 2n3005-type transistor, 10k linear pot, and 2 50 V diodes?

I'm making my first board circuit robot and I have to adjust the super small potentiometer that looks completely different from this one, I'm confused, I don't get anything anymore, I've been working on the same "scooter" robot from graymark over half a year and I haven't finished! What I have to adjust is the potentiometer vr1 to its center position how do I do that?!!!!!
