Join Michael Lehman for an in-depth discussion in this video Connecting inputs, part of Android App Development: Internet of Things.
- Once you've got your CPU, memory and timers figured out,…now you have to connect up inputs,…if you're going to have sensors on your device, to your CPU.…You connect up your inputs in a variety of ways.…There are analog inputs that measure changes in voltage.…This is something different than a typical digital input…which measures zero or one, or maybe some fixed number,…like a knob that goes one, two, three, four.…An analog input can measure a change in voltage,…and typical analog inputs are power supplies,…light sensors, potentiometers,…knobs that can change a variable amount,…think again of a volume control on a radio,…and then static digital inputs.…
These are things which, basically, can detect…whether there is a presence of a signal or not,…and then, finally, there are some kinds of…advanced digital inputs.…This is the kind of thing where you might have a sensor…that has multiple sections of data to send you,…so there are a variety of sensor standards.…There's one called SPI, for example, that allows your sensor…
