In this video we look to get the temperature sensor reading from the Raspberry pi pico onto the SSD1306 based OLED.

HEY YOU ABOUT TO POST SOMETHING STUPID:
Yes, I know my hands are large/fat. It's because of a heart condition I suffer from called Congestive Heart Failure. Here's a link to some information about CHF: cle.clinic/2TdS2Ux
One of the symptoms is that is causes fluid retention, mostly in the hands, feet/ankles, and face.
It will kill me one day. I'm doing ok right now, but someday...

Great to see another of Paul's Pico Python Practice lessons.
I particularly like the way you are, as the best teachers do, including what we learnt last time in each new lesson - rather than just jumping to a completely different content !
Maybe next time install a separate temp/humidity sensor such as the DHT22 to form a simple sort of weather station?
looking forward to learning more about using the Pico along with you & the rest of the LE family
Looks like a good introductory test of the Pico, nice job getting it working!
Liking what I see. Love the built-in temperature sensor. Still waiting for mine. Thanks, Paul.
Very cool. There may be hope for the Pico yet. Thanks for the video!
Writing code for the pico seams easier and harder at the same time. Great video Paul, thanks for all you do.
Thanks for your videos,very informative.Hang in there with your CHF.
Finally got my raspberry pico ..... gonna try it in the AM..... thanks for the video...
Love it when you spend a substantial mount of time planning and building then troubleshooting a project. To turn something on and get it working is like a miracle! I built an amplifier a few weeks ago and at first I had a tube go bad then the resistors charred and I was encouraged since the first powering on was successful and the audio was so nice and loud. I ordered a tung-sol 12ax7 and plugged it in last week, it works flawlessly. Now I gotta build a speaker box and mount the guts into a chassis. I’m able to adjust my B+ voltage for the plates of the tubes, I was screwing with it this morning and I found that with 400 volts to run the power output beam tetrode I can put 200 volts through my 12ax7, but the cathode-heater resistance is rated for 180 volts I still need to measure this reading. Do you know what the ideal plate voltage of the preamp triode would be for optimal tone for a line-level audio signal like a Hi-Fi amp or is it higher or lower than this if I try to plug in an electric guitar or how about a condenser mic?
Fantastic!
Unfortunately I have to wait a bit for the delivery of SSD1306.
Love to watch you work your way thru these as I watch them on my phone. Could you make the font of your code a little bigger? It's really rough on my eyes
I have been looking for weather related projects. DroneBot recently did a video on making an anemometer and I find all kinds of temperature and humidity videos with an occasional barometric pressure reader. However, I have found nothing for a wind vane, giving wind direction! I was wondering if that could be done with a rotary encoder. Or is there something easier? Also, looking for a rocking rain gauge, which could use either a magnetic reed switch or a LED/light sensor pair. And, finally, remote it all via wifi or some such. Either a PI or an Arduino. Not much, a bit less than the moon!!
Thanks for creating and posting, one of the better "how to" videos for us noobs.
I added and changed a couple lines to get readout in F. It works but not knowing what I'm doing there might be a better way...see below:
reading = sensor_temp.read_u16() * conversion_factor
temperature = 27 - (reading - 0.706)/0.001721
temperature_f = (temperature*1.8) + 32
print(temperature_f)
utime.sleep(2)
Can you explain why every demonstration of displaying temperature using the Pi Pico shows 5 places after the decimal place. Surely the information after the decimal point is totally pointless and irrelevant...I can understand one place after the decimal but not five. Is it laziness in writing the code or is it a case of not understanding the use of "int" or "float" when describing the variable values??? Otherwise loving your videos, especially about the Pi Pico and uPython
You'll be able to demonstrate this on your breakout board. Liked your calibration technique! 🤣
Nice program. Insert probe outside and have Pi light a BIG RED FLASHING LED when temperature drops below 40.
Have a great week Paul.
Its supposed to be 68 on Wednesday. I'll be out getting a tan in the backyard.
I wonder how to get rid of that blinking. That doesnt happen when printing real-time floating values to an OLED from Arduino. Also, the Pico can log data to its flash mem, so Im going to try to add that function to this program
It would be so much easier if the board was marked on top with pin details, thanks for the videos
Good one 👍🏻
If at first you don't succeed, hit the keys harder! ;-) I have to get one of those to play with.
Ive been messing with this particular thing for past few days and have managed to make the readout display cpu temp,ultra sonic distance range value , I even had a little pixel moving up down the screen depending on distance, The only issue im having is i cant find a way to make the text bigger on the screen.
Yeah, this library doesn't seem to have many different types of controls for the display. I've been thinking of trying out CircuitPython. You ever play with that?
@@learnelectronics I did put that into my pico but then windows refused to have compatible drivers to communicate with it so i had to revert it back to the original firmware. I think to use that id prob have to use Linux for compatibility issues.
@@learnelectronics Did you make any progress with making bigger text? i haven't yet.
👍
Where can I submit video ideas?
Arduino0169@gmail.com
pls give code
No Intro? Ok then... Lol
You thinking about it all wrong Paul. You didn't screw something up. The fingers and brain are not always on the same page... Lol
At a boy! I know you could do it! :-D
Thanks for the video!
LLAP
Are these celsius?
Yes
where did you print the pinout?
Off the internet
@@learnelectronics can you provide the link to the picture?
Hoping my Pico's will turn up soon, also have Zero W's on backorder ... yawn, I hate waiting...
meanwhile you got time to do some research (if you need it)
You need to borrow AvE's voice activated camera.
