arduino or raspberry pi, which one?

[Shox Dr]

Summarised quite well by others - the Raspberry Pi is basically a tiny computer (actually a pretty powerful one these days) but with some easier to access hardware for controlling things. It's trivial to connect things like cameras, USB devices etc to it like you would on a computer. For example a couple of evenings ago I knocked together a motion detecting trail camera like thing to put inside my Mum's duck shed, something had been attacking the eggs so she wanted to see what was going on. Raspberry Pi 4, Camera, DC switch mode supply and an old tractor battery to power it, together with a bodged together case. The Pi even acted as it's own WiFi hotspot so I could see the picture on my laptop or phone next to it (it was the other end of the yard to the existing WiFi signal).

The Arduino (there is a better alternative) is basically if you want to talk and control electronics at a lower level - controlling a remote control vehicle or something like that.

I wouldn't use an Arduino though for that kind of stuff - they're not that cheap anymore and you can use ST's Nucleo boards which are pin-compatible with the Arduino's, can be programmed using the same environment, much more powerful processor and under half the price last time I looked.

Totally OT. We used to breed Pheasants, ducks etc. Best way to stop either birds or vermin from eating eggs, is to blow one out and fill with english mustard. They soon stop pecking

I started from scratch (ie zero computer knowledge) and ended up with a pre-war Austin seven revcounter, temp gauge, oil pressure and warning lights. Wish I could have got an Arduino ignition system. Would save a lot of aggro.

I think there is a group that has done this - speeduino* if I recall? As I said, ignition is a lot more complicated than fuelling, if easier to set up maybe once you get it working. You have to convert time/rpm into degrees, continiously.

So what had been going on? Do tell...

The two females were fighting each other. These are muscovies so vicious little bastwerds.

Yup, speeduino. Was quite interested in that project until I started delving into the possibility of porting it to ST / Arm. Rather than use a more powerful (and cheaper) device they've gone out of their way to "optimise" code for the less powerful device therefore shooting themselves in their foot.
