Include at least one input and one output device. <br> 2. Write a microcontroller program that integrates at least one input device and one output device. Avoid the <code>delay()</code> function and use the C++ class structure. <br> 3. Use an oscilloscope to discover the time domain at which your output device is operating. Is it on a fixed clock? What's its speed? Share images and describe your findings. <br> </p> Examples: [Isa (Plant Waterer)](https://isa-gooijer.github.io/PS70/07_output/index.html), <a href='https://kian2attari.github.io/2020/03/14/week-8.html'>Kian (pan/tilt kit)</a>, <a href='https://kassialove.github.io/PS70-assignments/week8.html'> Kassia (RGB LED / buzzer)</a>, <a href='https://tsevilla16.github.io/TeddySevilla-PS70/week8.html'> Teddy (LED Strip / pot)</a>.
