To.tobias : Question about "Measuring propeller RPM: Part 1”

Post by SJULEE »

Hello! I'm studying alone in Korea about measurement of RPM of Crazyflie 2.1.
I saw a post about "One comment on “Measuring propeller RPM: Part 1"
And then I following the picture you developed.
But I have 3 questions that I cannot understand.

1.Is this resistor "Thick Film Resistor" used"?
If that used, Can I change the "Carbon Film Resistor" generally?

2. In Prototype deck, If I solder in 1(row)-A(column), Is hole 1-A connect with pin 1 automatically?

3. What do you use scope program in the post?

Hi!

I will try to remember :-)

1. Yes you can use Carbon Film resistor instead

2. Yes

3. To verify the output from the sensor. That it detects the spinning propeller and that the signal looks good.
