Do we have any Arduino/C++ coders here?
I’m working on a small personal project called wildcat, designed to function in a similar way to the “days since last incident” signs you often see in factories:
…but to track how long it’s been since our new cat has last misbehaved! (She’s a bit liberal with her claws).
The approach I’ve taken is to use an ESP8266 (Adafruit Feather Huzzah, specifically) with a 16x8 LED matrix to display how long it’s been since the last incident, with a button on the back which lets you reset the timer.
Behind the scenes, this is using Adafruit IO to store a timestamp of the latest incident, which it then uses to calculate how long to show on the display.
(I’m sure I could have done all this locally with a different type of Arduino, a real time clock, and some non-volatile memory, but I don’t have any of those things - plus this gives me the benefit of being able to do things like add Alexa integration at a later date).
Anyway, it’s software side of things is pretty much done (at least for this stage), I just need to figure out the best way of assembling it all - but for now, I’m hoping someone with some Arduino/C++ experience might be able to take a look at my code, please?
I’m using PlatformIO, so if you’re not familiar with this, just take a look at my main.ino file.
I welcome any and all feedback. I’m quite proud of what I’ve gotten so far, but I know it can be better.
