I'm constructing a little mobile for my baby son and I want it to turn 3 times forth and 3 times back. When I apply other angles to the arduino sweep example, it doesn't work. Can anyone help me?
[...] I need one that turns at around 5 RPM. Do you have an idea?
It should move a mobile that weighs around 1kg and is about 40 cm in diameter. The mobile will be attached via a string, so there will be a delay in action.
Oh, I would be very interrested to see some pictures of that mobile.
No, the baby ist not lying directly under the mobile and it doesnt weigh 1 kg, but at some time he might grab something spinning, so I wanted to give you a kind of maximum weight. I'm a german and in germany the limits always exceed 10 times reality
Right at the moment im using a stepper motor from an old printer and I'm trying to program a speed control using a rotary controler, which only eventually works. I'm pretty new to this microcontroller, arduino business. Maybe you have an idea regarding my code and eventually how to add a speed reduction before going the other way. (see below)
