Well done!
I think the whole world got a little smaller! (or more Disney!) 😄 👍
That was REALLY AWFUL, James!!!😁😁
Thank You, I thought so too. I had a problem with the audio. The buzzer would not record, I finally used the camera phone. Not ideal but it worked. Now that is a tune that will stick with you. LOL
Indeed, an annoying song. Well done!
WOnderful !!! Could you share the program, please?
I will try to upload to github
here is the link to the github: github.com/n6dbq/Arduino_R4
Hahahaha 😄 Brilliant 😊👏👏👏👏
Thanks 😆
Nice Solution! I like the on/off slide switch for the buzzer. Also nice touch with the Display. Great to visualize things. Kind Regards from Calgary Alberta Canada.
Thanks
H James I like your little screen and also how you can turn the annoying buzzer off. Unfortunately, you've got your timings wrong. dah should be on for 3 units and off for 1 unit. Also, you turn the buzzer off for 1 unit at the end of dit and for 3 units (should be 1 unit as I said above) at the end of dah, therefore the delay after each letter should be 2 units. This is probably why you found it hard to hear the pause between each 'sos'. If you fix these bugs, I think that a delay of 7 units would work fine. Obviously this should be coded as 6 units because of the i unit delay at the end of the last dit in 'sos'. Sorry to be so negative😿😿
Not negative, just informative. Made those changes and it worked perfectly. Thanks
@@jameslewellen150 Hurrah!!!!
Cool video. I like the way you used the tft screen. 👍

Well done!
Thanks
Excellent!
Many thanks!
Hi James I like your little screen. Just one thing - you don't need to work out the low and high grades because you could just use grades[0] and grades[numGrades - 1]
Nice job! Thanks for posting.
Excellent!
Pretty Cool! 👍
Great homework ..thanks for posting . Like the TFT display , will be investigating 😉
The tft display library needed a change to Adafruit_ili9341,cpp look up the error code wiring_private that initially comes up and search on that. The fix to that file works. I fixed the file and saved it separate from the library so if things go wrong I have the updated file. Link is: forum.arduino.cc/t/compilation-error-wiring-private-h-no-such-file-or-directory/1146752/2
Nice work!
thanks
Excellent!
I believe there is a function called sort() that will arrange all elements of an array into order 👍 Just thought I would let you know in case you want to mess around with it a bit 👍 Have a nice day 👋
Very good 👍
Big thanks ❤
Excellent!
Nice job and quick too. I have not tried but you should be able to put sm0.put(0) as the first line in your except to clear the LEDs then maybe a short sleep before sm0.active(0) Thanks for posting
That worked nicely. Thanks
Great job!🎉
🤩very bright 🤩 good work! 👍
Nice job James. A couple of things. In lines 23 and 40 you spell tDown as tDwon. That may solve the problem. If not you may need separate variables for tUp/tDown for each callback like tUp2/tDown2. Thanks for posting.
I tried both fixes and no success. Still has that extra bit before changing direction. Perplexed
@@jameslewellen150 Ah I see you need to put the increment before the led.values in both callbacks
@@keithlohmeyer Nice, works now. Sometimes I am braindead. I guess that comes with age. Thanks
Been following the series, thank you!
Very nice! Thanks for posting.
good work, grandpa 👍
I am kinda older than dirt. lol
Thanks for the video! Good Stuff! 👍
Nice!
Thanks for a nice solution and also showing the bounce from the button on your oscilloscope!
Nice job!
Excellent!
It's really cool to see someone getting started with programming like this! Best of luck James!
Nice!
I should have used variables as time values. Not that complicated. Thanks
Jolly good, James
Thanks
Very nice 👌
Excellent!
Well done! Love the massive breadboarding setup! Love the font size on that display!
Interesting approach. The challenge is going to be that the way you did redBlink is now blocking. the time.sleep of .9 is going to halt your program, and anything else you do in the main while loop. Take a look at my solution next week.
I think this program works fine and is a valid solution for the homework. But I agree that there are other better solutions, giving the posibility for the Picow / main program to do more than just blinking one LED.
LEGEND!
Thanks
Excellent!
Many thanks!
Cool!!!
Excellent!
Nice job. Sound like you have your RPi4 working overtime. Thanks for the video.
The RPi4 works for most things but os studio and video editing it is strained.
Very cool, including the OLED display! 👍
Very nice, James
Super cool 😎 👌
