1) Issues with the sound device were solved. Before, the sound kept going off even when an initiating signal stopped being sent. We realized that we needed to add a 10K resistor to the sound system as a ground because it eliminated the lingering initiation signal that kept setting the alarm off. With this fixed, the pin signal sent from the timer on one board could initiate the beeping on the other board.
2) We then moved all of our LED Array components onto the secondary board to reduce clutter on the primary LCD board. Now, both the LED Array and sound are initiated by a single signal from the primary board that is sent when the timer hits 8:00:00.
Issues moving forward
- Need to finalize physical arrangement for casing design on solidworks
- Currently, at 8:00:00 the alarm mechanisms are triggered but then cease after one second. We're having difficultly programming the board to continue the alarm even after 8:00:00 has passed
Below is a video showing our potentiometer controlled fan and alarm system going off at 8:00:00.
We have had significant issues dealing with Github up until this point and as a result we have been unable to post our code and the progress we've made. We were just recently informed that simply posting the code in a post is acceptable, so the next two posts will contain our code. We apologize for this delay
