like a pitot tube for airspeed?

AnonEngineeringOP•1/3/25, 2:55 AM

i just did a quick Wikipedia on it, looks like you need to measure differential air pressure, so you need two

MMik I see, is it possible to damage the board by putting in code that is wrong?

shouldn't be an issue unless you're messing about with flashing bootloaders from random HEX files....

as long as you're using the Arduino IDE then it should be reversible as long as you select the correct board before uploading your code... (procedures that are covered in Paul's tutorials) ...

so long as you can read in those values and convert them to an analog voltage, sure
will it sound like a symphony? not so much

AnonEngineeringOP•1/3/25, 3:54 AM

an Uno has a 10 bit ADC, and ESP has a 12 bit ADC, this sets the maximum value

AnonEngineeringOP•1/3/25, 3:54 AM

so an Uno will read 1024, an ESP 4096

AnonEngineeringOP•1/3/25, 3:56 AM

yes, was just illustrating max values versus bits

@DoctorO9 belts ?

AAkithmari Technically yes but i got dumd faces from my instructor saying that.

If start looking into it that's really what's happening both in software and in hardware

AAkithmari Electronician and arduino use PWM to decrease voltage.

KLevi•1/3/25, 8:44 AM

That's just not true. With PWM you just decrease the duty cycle.

AAkithmari Not entirely wrong. But for correct statement its actually a modulation.

KLevi•1/3/25, 8:45 AM

Yeah, you are modulating the time duration when the signal is high and when it's low.

KLevi•1/3/25, 8:46 AM

So the best answer is spreading misinformation that PWM modulates the voltage?

KLevi•1/3/25, 8:48 AM

I mean that's what the Arduino core does aswell calling it analogwrite but I don't think they say that it's affecting the voltage
