🎄 Day #5: Switch the DIP!

Today, we added a “rat’s nest” of jumper wires and a 5-way DIP switch. We can now physically turn each LED on and off individually. Also, using functions we can run little programs for each DIP switch.

🎄 Day #7: Time to Slide!

Today, we added a slide potentiometer “slider” to the build. We changed the LED colours, fades, and flash speed. We used the ADC pins on the Pico to turn the signal coming from the slider into digital.
