Adafruit Alarm Clock

This project encompasses a adafruit CPX that is programmed as an alarm clock that is light sensitive. This alarm clock will be used to wake up an individual with the sun by making noises and flashing lights. This product is supposed to be interactive and help one live a healthier sleeping lifestyle.

To use the same holder than we used for our project, you need to go to thingiverse.com and search for the CPX holder. The exact one that we used is in the photo attached. If you want to use a different holder you can but you just need to make sure the sunlight will be able to reach the light sensors on the CPX.

Print holder, but make sure it's to scale. The holder needs to be the same size as your CPX so it will fit in the holder and doesn't need to be printed with supports. To print this you need to go to tinkercad and upload the file there to get a .stl file to bring to the 3D printer.

The code attached is the code used to make the CPX work as an alarm clock.

# Threshold for light detection

BRIGHT_THRESHOLD = 200 # Adjust this based on your environment

while True:

# Check if the light level is bright

if cp.light > BRIGHT_THRESHOLD:

for _ in range(10):

# Play a siren sound - simulated by tones (no siren preset)

cp.play_tone(880, 0.2)

cp.play_tone(440, 0.2)

# Show a rainbow-like pattern on NeoPixels

colors = [

(255, 0, 0), # Red

(255, 128, 0), # Orange

(255, 255, 0), # Yellow

(0, 255, 0), # Green

(0, 255, 255), # Cyan

(0, 0, 255), # Blue

(128, 0, 255), # Indigo

(255, 0, 255), # Violet

(255, 255, 255),# White

(0, 0, 0) # Off (optional)

]

for i in range(10):

cp.pixels[i] = colors[i % len(colors)]

cp.pixels.show()

time.sleep(0.2)

# Optional: turn off pixels after

cp.pixels.fill((0, 0, 0))

time.sleep(0.1)

To put everything together you need to get all your materials in one place. To start, you need to download you python code onto your CPX using the USBC cord, once you do that you need to take your battery pack, with batteries already inside and connect it to the CPX so it can run without the power from the computer. Next, you can put your CPX into the holder and hot glue the battery back to the underside of the holder so it doesn't interfere with the sun getting to the light sensors. Once all those steps are completed, you can put your CPX in a place where there'll be light in the morning to have the alarm clock go off to the suns rays.
