I have a project in mind, where you could turn LEDs on and off by moving a magnet close to the thingie. When it’s on, touching the box with a magnet would turn the LEDs off, and on again with a second touch.
I’m pretty confident with programming, but not so much with electronics.
Looks to me that building a circuit for this with an arduino is quite straightforward.
Now, without an arduino, if I got it right, I’d have to build a flip-flop circuit. Looking at this website, it can get pretty involved. Almost daunting.
These are my pros and cons for each approach:
- Price: without an arduino it would be cheaper, since I want to build a few of theses
- Complexity: with an arduino I don’t have any worries. But without one might be over my skill level
- Size: The complete thing should be as small as possible (say under 5cm). It’s kinda clear how small arduino boards get, so actually it feels like the flip-flop piece would take up more space (Compared to Flora)
- Power: Because of the size limit, there’s not too much space for batteries. An arduino would definitely would require more juice.
- Parts: Without an arduino, I’d need a lot of different components I don’t have at the moment.
This is just a list of educated guesses, so I’d love to hear your input, on which way to go.
