Arduino fun
Recently my Garmin watch strap snapped, so I figured I’d order a replacement from Temu. Naturally, while I was at it,
I also ordered an Arduino Uno kit. :D.
Although I’m officially an embedded software engineer at my company, I haven’t done much real embedded work for
years now, and I kind of miss it. So I wanted to play around a bit.
I used a DHT11 sensor to read the temperature and humidity in my room. I then combine those values to get a rough
sense of the “state” of the room and signal that state using 3 LEDs. Green means everything is good, yellow means
it’s not ideal, and red means it’s getting hellish. :D. The DHT11 timing was more sensitive than I expected, there
was some trial and error involved before I managed to make it work.
The result:
At some point I’ll get a few more components, definitely some kind of display, and continue playing around. But for
now, this was a fun, refreshing little micro project.
Aside from that, I also made a couple of other examples. The source code for all of them is here:
