I am trying to control a bunch of devices through an app on my phone. I was planning on using the MKR1000 to connect to my phone via wifi and then use that to control an Uno that would run the device. Is that possible or am I going about this the wrong way? Thanks.
How shall the MKR1000 talk to the Uno's?
What's the maximum distance between the controller and devices?
Using USB-serial requires one USB port for every connected device, doesn't look like a good decision. If USB is not used, a smaller board can be used for the devices.
I thought there was a way to connect the MKR1000 to the Uno by connecting two pins, like having the Uno being a slave to the MKR. To be honest I am not sure how that works exactly but I have found examples where people slave two Unos together by connecting pins.
A serial connection can be made in several ways. For multiple slaves e.g. I2C could be used, using the SCL and SDA pins of every board.
