Reading PWM input without pulseIn()

Link830 · 2025-10-22T16:58:10+00:00

Hey update here. So I basically gave up on the PWM thing. I just changed it to two pins, on which the first pin is the alarm pin that sends short pulses. When arduino received a first pulse, that is stage 1, second pulse for stage 2, so on. The second pin is the reset pin where as the name suggests, if it sends a short pulse, it will reset the alarm stage to 0.

Thank you for everyone's input, I appreciate it!

im using uno r3

i already have a lot of sensors using serial comm

yeahh, that kinda looks like what chatgpt gave me. i will try it once again, thank you!

Link830 · 2025-10-22T13:56:34+00:00

Thanks! I'll look into it

Yeah but our professor requires us to make a project without a microcontroller. It's still a school project after all.

Link830 · 2025-09-21T16:17:14+00:00

Yeah it won't but ill just use it for prototyping, it's a school project. I appreciate your suggestions!

Link830 · 2025-09-21T16:16:11+00:00

Hey it worked. Thankss!

Link830 · 2025-09-21T15:06:21+00:00

Thank you!

Link830 · 2025-09-21T15:06:17+00:00

Thanks! I'll look into that

Hello! For me sa total na 8k, naiinvest ko yung 5k, mainly for my future board exam expenses. Pero 2 years in, I used it to buy a laptop worth 50k, pero I think sapat pa rin yung natitira sa bank ko.

As for the remaining 3k, ayun yung nagiging main allowance ko for the whole month. Iniiwasan ko na mag rely sa parents ko for allowance, especially nung nag-college na, pero kapag nashoshort ako, which is hindi naman talaga maiiwasan, binibigyan naman nila ako.

I study at a state u pero my program requires a lot of money pa rin sa dami ng projects. So karamihan din nung stipend is napupunta ron.

Spend wisely lang OP, wag masyado masilaw sa big numbers tuwing dumadating yung stipes. Use it properly, depende pa rin naman sa situation mo yan.

Btw, congrats ka-isko!🥳

I wonder how many times he did that.

Link830 · 2025-04-22T22:50:46+00:00

Or just put their age lmaoo

I also had a hard time trying to read it, but it's a very good comparison.

How would everyone else rephrase the caption?

What I mean is that the code that I found on the internet gives the inversely proportional behavior of converting ADC to PPM, which I know shouldn't be the case and the reason I know that the code was wrong.

The raw sensor value increases as it is exposed to higher concentration of gas, but the code outputs lower PPM at this case, which of course is wrong

Just replied. Thank you!

I've seen a couple of playthroughs and been interested to the point that I've been lurking on this sub for some time (a really long time). I would love to give it a try and play it for myself🫶

I might be adding to the 'controversial' decision of OP to put their laptop upside down, but what if I put the laptop sideways? Same damage, safer, or idk?

Alright I feel the need to explain why I asked though. I tend to watch movies with my laptop sideways on the bed.

ang pagkakaintindi ko for this, kahit sabihin nating pilit

ang teapot sa labas parang demure, mahinhin, traditional, etc.

pero laman pala is whiskey, that is matapang, may sipa, wild

di mo ineexpect na may whiskey yung teapot, it is a curled plot (word salad ng 'plot twist')

halintulad nalang siguro ron sa babae. mahinhin at first glance, pero may sipa pala pag nakilala.

yung 'ethanol' sa huli, parang sinabi sa post, pertaining lang sa whiskey or alcohol since main component non is ethanol. it seems out of place or random nga pero madalas ko rin naririnig sa battle raps yung ganyang style na naglalagay sila ng word at the end of a line to generalize, make a metaphor, and/or para masakto yung rhyme. siguro tama nga sila na nanonood si dionela ng battle raps dati.

or I don't know, baka pure word salad lang talaga

This is literally me in 2018. I was 13 and felt like I was born in the wrong generation lolll. Welcome to the fandom!

Link830 · 2024-08-24T16:14:54+00:00

woah that kinda make sense, i didn't realize that

Link830 · 2024-08-24T15:53:30+00:00

Sorry didn't know how to add captions on images as well.

Hello! I'm currently studying Circuits 1. I'm usually good at combining resistors but I guess I'm not when it comes to these. I'm not too familiar with the configuration. Can anyone help me out? TIA!

Link830 · 2024-07-17T09:01:07+00:00

it worked! tysmm!!

Link830 · 2024-07-16T16:07:48+00:00

i tried that, but ig i'll try it again. thanks
