I've recently made an orrery (dynamic model of solar system) using a mega which I can upload sketches to with bluetooth and wifi. This is a requirement as the device is 3 metres off the floor. Sadly the processing power of the mega struggles to get all 9 stepper motors at full speed.
A due would solve my problems but I haven't managed to find a way of uploading sketches using OTA. I've scoured the forums but wanted to ask the question directly. I could consider using a second controller, even a rasberry pi if I had to, to upload the binary if there was a route in. The bigger boards are needed for the inputs, I need a few as there are seperate encoders and motors for each planet. Wires all over the place.
Any thoughts from the wise most welcome.
