Morse code project needs to be expanded! Great stuff James! Marking this watch later till I can find a couple of these boards available. Camakit says a month on preorder.
I'm already looking at ways to build a system to send a receive with a pair of them. Although, I'd we are being honest, it might be better suited to an ESP32 with its built in wireless tech.

Hope you loved this Pico video! Want to see a robot arcade cabinet that has its controls based on the Pico? Check it out here! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kwSVW0K3BZY.html
Thank you for these truly imaginative and well presented examples of what is possible with such a low cost, accessable little board. I wish you and the Pico had been around 60 years ago when I was a kid! Now THAT would be a trick!
One tiny niggle: the ratio of long to short in morse is 3 to 1 not 2 to 1 as your code appears to specify. The inter-element spacing should be one short and the inter-character spacing one long. Inter-word spacing is basically anything over 3 longs. However, every morse operator has their own 'fist' or style and that is determined by how they space elements and characters/words. For instance, I tend to lengthen the long in the letters 'f' & 'l' to 4 or 5 shorts to change the rhythm. Machine generated morse is very recognisable on air as it is very boringly exact ... unless the code generates some random, small differences. 🙂 But great projects. Does MicroPython not have the += construct? I noticed you didn't use that.
It would be awesome to add another unit And add some listening code code for inbound messages. Turning this into a semi encrypted transmission device using walkie-talkies. You would also need a keying line of code. Possibly some resistance for the speaker wires. Worth the research and it would be pretty neat if you could get it to work!
Thanks for such a well presented, excellently clear and informative tutorial. More of the same please. I'll be checking out your other channels and videos. Best regards.
Can you build a drone using pico and build a gyroscope and a flight controller? can you also do the control circuit with the NRF and control the drone? Would be a legend
great video. building along with you. I think this pico has a damaged thermistor, maybe done by me when putting on the rails. The room I'm in is 73f / 22.78c , but the one i've got in my breadboard is reporting about 15c... meanwhile another un-touched pico is reporting 22-23 ... -_- I didn't linger on any of the pins excessively with the soldering iron, and the other two projects work great. very weird. guess i'll try to solder this known good one and see if i destroy it or not.
Nice pico projects, can You show how to write or read multiple i/o pins at once ? I looked in the rp2040 datasheet for this but can't figure it out yet.
Sorry about the code. It was pointed out to me that it's only clear on a 1080p display and not great on phones. The code is provided in the description, if you want to see it yourself. Let me know if you have any questions
Nice set of projects. I have one question, why is the conversion factor for voltage 3.3/ 65535 ? I read that the Pico has a 12 bit ADC so why is the conversion factor not 3.3/4095 ?
Excellent question! While the ADC does, indeed, return a 12 bit value, its converted to a 16 bit value with MicroPython to keep compatibility between other boards running MicroPython. Here's the relevant snippet from the Pico Python SDK An ADC has two key features: its resolution, measured in digital bits, and its channels, or how many analogue signals it can accept and convert at once. The ADC on RP2040 has a resolution of 12-bits, meaning that it can transform an analogue signal into a digital signal as a number ranging from 0 to 4095 - though this is handled in MicroPython transformed to a 16-bit number ranging from 0 to 65,535, so that it behaves the same as the ADC on other MicroPython microcontrollers.
5:40 nope, ADC(4) is not on pin 4, it is the fourth ADC project suggestion, play sound from file, not embedded, scan for music files (*.mus), show list, select, play
Will the Morse Code .... code work on a normal Raspberry Pi, my local Pico supplier they are out of stock right now. So in the mean time I wanted to play with that morse code program
@@PrintNPlay This is quite subjective I have age related hearing loss, so I don't pick up high frequencies, but to rule that out I got the windows sound settings up and watched the level indicator - it only moves a few pixels during the speaker sections, but your voice shows up just fine, thought I'd ask around, if you can hear it while viewing on RU-vid then its all my end.
Totally understand. I will make sure audio levels are better in the future. Thanks for taking the time to let me know, and sorry that the audio wasn't better in this one.
This is the kind of stuff I wish we did in my electronics class or was a option back then. This is the stuff I would've lived for back then and would've made overthinking with programming less of a issue as it is now XD
Hey man I have a question, I am trying to make a wireless game pad for Commodore 64 and Nintendo nes, ignore the wireless part, how do I make a game pad for a retro system with this thing if I plan to add wireless later? I’m confused where to start
Sorry about the delay in reply. I've actually been working on a dual USB / C64 joystick controller. Be glad to fire you some info if you want to send me an email! Printnplayjay@gmail.com
Thank’s for your very clear instructions. You are an exception, most others does not e.g. Explain. What Pin is, they just put it there. The same with the way the tones are created. GREAT!
I enjoyed this video. A good follow up would be a blog post that goes a little more in depth explaining a bit more of the underlying theory and why of things. I get that there are resources out there for beginners already. I just think you would be particularly good at creating that sort of content.
James I can see the last part of the 3rd project as a memory keyer and a morse trainer. Maybe a future option for Iambic paddles or straight key? Iambic reads two inputs where ST K reads one.
Great video and explanation. Can you do a project with timers for ralais , external temp sensors , ph sensor , flow sensor . .. for a small reef tank controller something like reef pi but more basic and cheaper..
So, since only one led is illuminated at a time, it's okay for them to share a resistor. And since it doesn't matter which side of the circuit the resistor is on, as long as the LED is connected to it, I tied them at ground level. Basically, I was trying to do it with as few components as possible. Hope that makes sense!
I wonder, when I have a line like temp = 27 - ((currentvoltage - 0.706) / 0.001721) can the measured temperature ever be above 27 deg? I currently have above 29 deg C and the pico thinks its 21.4 I know this is not a precision device but thats really to far away from the real temp.
If you "save a file to the device" and give it the special name main.py, then MicroPython starts running that script as soon as power is supplied to Raspberry Pi Pico in the future. datasheets.raspberrypi.org/pico/raspberry-pi-pico-python-sdk.pdf
T.Kawasaki Great video, thanks. But when I tried the third example, I had an error massageI, that "MusicNotes" is not recognaized. How I can soleve this?
I am new to python and micro python, where can I find a reference to the commands available to micro python. I need to know the syntax of said commands and any variations of the code.
I will have C content coming in the future, but Ben Heck Hacks has been doing some with it and he's super knowledgeable... If you're not already following him, definitely check him out!
Hi, the simplicity of this video makes me want to play around with Pico too. How about making Pico a standalone and not dependent on a PC, is that possible?
@@PrintNPlay Blessing in disguise, all the extra comments drive up your interaction rate. :D GO RU-vid ALGORITHM! lol I have subbed and I appreciate the beginner project to get used to the Pico!
Not sure if you are kidding or not, but here is the creator of Python talking about it and calling it pie-thon. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-J0Aq44Pze-w.html
Great video, thanks. But here are some comments. It IS a standalone computer, just not a desktop computer with an operating system. I wouldn't put the components so cloes to the Pi, those connectors on the side could shortcut to the led. I also usually prefere to use the red tracks as positive and blue of the breadboard as ground. That will make me do less errors. PWM uses constant frequence, but varies the propotion between how long it should stay high and low. But the frequence are the same in PWM. But as you have in your code, you can also change the frequence in those PWM ports of this RPi software. Why don't you use the RPi B model to develop this on? :-)
All good points! I think how the term "computer" is used has definitely changed over the years. Although, even with the adoption of what is presently considered a computer, the Pico is fully capable of emulating older computers and being useable as such so... Hopefully the point wasn't lost, if for a lack of more appropriate phrasing. Spacing of components is definitely important. Don't want to short our the device, or the USB port it's connected to. And finally, I do enjoy coding on my Pi 400, but it's been easier for me to do screen recording on my desktop. Thanks for taking the time to share your thoughts!
@@PrintNPlay thanks for the comments. Yes, this little computer have the capacity (and more) to emulate a PDP 11 minicomputer (that is real mini computers ) Computers that run original Unix, with serveral concurent users. :-) Has actually run Unix on one and have also been in the CPU of a PDP 8 and fixed a problem. The CPU was about 2 meters hight, in a full 19" rack. I nealy fitted into the CPU. :-) Yes, that was about 1993, and these computers was already old then.
