My sister in law is Irish and German.
She’s a generous soul and we wanted to do something for her. She likes to drink as well.
Someone suggested the façade of a church that dispenses the mini (50ml) liquor bottles. The dispensing part is essentially proven out. I’ve made it twice with materials that are more than in the final build.
Essentially there are 28 little doors that open and the booze slides down to a door where she can get it. I need to trigger solenoids to open the doors.
On the breadboard I’ve build 4 or 5 versions of the (4) 74HC595 circuit. I have had varied success. When working with just one IC and 8 LEDs, things are fine. After that it gets interesting for me. Anyway, I don’t think I’ll need help building the circuit.
The circuit is, of course where my problem lies. I just need to ensure lots of 0s sit on those pins until it’s time to drop a bottle. This happens once a day at 5:00PM EST, as it stands now. I’ve ordered one of those little clocks to keep the system close to actual time. We think she will get a kick out of it because so like to be precise. The ordering couldn’t be easier. I’ll be just working from solenoid number one forward until is reached. Well, I think it’s 26 days this year.
The leads from the 595s will trigger a 5V relay, which will allow the higher voltage to for a moment while the solenoid is active.
We may have to unlock the front door be we can add that in the future perhaps. There was talk of a recording of bells.
I also want to learn so as you move through the process please as notes in the code that can help me better understand.
What are your thoughts?
