Modify Arduino code (add piezo buzzer to a working digital hourglass)
$10-30 USD
Pagado a la entrega
Hi, I have a working piece of Arduino code for the Uno / m328p that operates two 8x8 SZ410780N LED matrices through 4 x 595 shift registers (standalone m328p schematic attached) and turns it into a digital hourglass.
The attached source code works great. It uses a pot to adjust the amount of measured time. It also has two tilt sensors to detect position of the hourglass and move the "sand" accordingly. There is a reset button to reset the countdown.
Now, what I need is a piezo buzzer added.
I need it to do the short "tick-tock" sound for each motion of the "sand". And I need it to make an alarm sound for 20 seconds - "beep-beep-beep" when all the "sand" has moved to the bottom piece (timer done).
Extra task: $10 bonus if you can get it to run on an Atmega 8 (I tried a few boards available online but it seems to work on the 328p / Uno only).
Feel free to ask any questions. Serious bidders only please.

Hello! That's an interesting task. Not sure if it can work on atmega8 without major changes. But anyway i'd like to do it. I have a mega and nano in my lab so i dont need to buy any hardware and can start job quickly.
