Devlog3 - Sleep Helper

What I did:

• Added a photoresistor for light levels + LED
• Added code to set an alarm + buzzer
• added a relay that would cause a motor to spin if the temperature got past ideal sleeping temps
• Added an extra button to stop/set alarm
• Added an ethernet shield because it has a microSD card slot
• Used microSD card to create a CSV file with timestamps, temp & humidity data, light etc.
• microSD card can then be removed from ethernet shield and opened to see data in an EXCEL spreadsheet (check how your sleeping environment was after waking up)
• added a capacitor to deal with voltage dips
• Debugged during Argentina vs England (🐐)
• Free up space for SRAM on Arduino UNO

(this has taken too long.)

MAJOR PROBLEMS:

• Arduino Uno doesn’t have enough SRAM to manage OLED, DHT and SD libraries at once and doesn’t have adequate space to Open a file on an SD card for a write function

Moving forward:

• finding a solution to manage everything without voltage dips becoming an issue + managing SRAM
• adding motor
• Creating 3D printed housing
• Shipping
