(sorry for the sideways video!)

And - I got the last five up and running! Glad I got the first batch finished. The went and were delivered to my kid’s 4K class on Wed for their first day back (And itheir Halloween party!) since being shut down as a classroom for Covid; only for the district to shut down ALL in person classes through the end of November.

The issue was that I could upload the boot loader on these five boards, but couldn’t program the via serial with a sketch. Tonight I went through and re-checked bootloading, checked for shorts, bad solder joints and solder balls and couldn’t find any obvious issues. After looking up the error code, I realized that I can program the chip over the ICSP header and don’t actually need the serial port header. I went that route and they all worked right away!

Testing them, I noticed that the five boards actually power up immediately without a 1.5 second delay. All the other boards have a delay. So the boot loader I’m using must not be setting all the required fuses. These five chips are skipping the startup delay and don’t ack the programmer to accept a new program. The ICSP header works differently and this isn’t an issue. So I now have 100% working fleet of scary ghosts! Perhaps I’ll investigate that later, but they’re working now [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-d703e666-29ff-48df-b19a-4d8830eae219/2642.contentimage_5F00_1.png:16:16]

OK- I have 35 completed! Powered up and running! Two are already delivered; and here are 33 more. This leaves five to go, which are assembled but wouldn't take the program. I only required 31 finished units, so I can troubleshoot the rest later. Phew! This was a marathon!

Very cool! Great concept and design. Looks like you still have a lot of work to do getting all the units built up.

I love your project. It was a lot of work!

I have a question though. I am trying to understand how do red LEDs blinking during the whole time notes are playing, not just at the end of each note.

Reading the code:

timeend = millis() + (songdurat[currentNote]*1000);
tone(Speaker, notes_hz[songnotes[currentNote]], songdurat[currentNote]*950);

So the loop is done only after time = duration * 950 is played, and only then you enter the loop again and get to call blinkLights() again.

I must be missing something but how do reds blink so often during the tone played?
