Project 1
Design and construct a circuit with a buzzer, seven LEDs, jumpers, and other necessary electronic components. Seven jumpers are connected to several GPIO channels as capacitive touch pins. Each jumper represents each musical tone of the seven tones (do, re, mi, fa, sol, la, and si). Each jumper is also connected to a LED. When one of the jumpers is touched, it plays its musical tone, and its corresponding LED is lit. Capture your settings and working circuit in photos and videos (the videos should include sound).

This project is about designing and constructing a circuit to help you wake up in the morning. Use a LED, a NeoPixel module, a buzzer, a photoresistor, a button, and other necessary electronic components. When it is dark, just the LED is lit (probably with dim light because you need to sleep well). When it is bright, the NeoPixel module blinks all the LEDs fast at random, and the buzzer makes loud and crazy sound until the button is pressed (when the button is pressed, all the LEDs stop blinking, and the buzzer stops making any noise.) Capture your settings and working circuit in photos and videos (the videos should include sound).
