(Choose one) - <a href='../../lab/output/led/rgb.html' target="_self">RGB LEDs</a>: Control each color channel independently. - <a href='../../lab/output/led/strip.html' target="_self">LED Strips</a>: Light the first 4 LEDs of your LED strip with different colors. - <a href='../../lab/output/display/oled.html' target="_self">OLED</a>: Write a function to change the screen color. - <a href='../../lab/output/buzzer/index.html' target="_self">Piezo Buzzers</a>: Compose a melody (3+ notes) and play it. - <a href='../../lab/output/speaker/amplifier.html' target="_self">i2s Speaker/Amplifier</a> (also see this <a href='https://dronebotworkshop.com/esp32-i2s/'>i2s tutorial</a>): Play a sound file. ### Assignment: <b>Minimum Viable Product:</b> Make a serious attempt at the most challenging/intimidating aspect of your final project. 1. Include at least one input and one output device. 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. 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.

Use a 'scope. Chat with your lab TA about programming assesment results. Confirm any materials you may need for your final project.
