• This folder contains code from early to mid 2025.

• This folder contains KiCad hardware design files

• This folder contains the microcontroller code, stored as a PlatformIO project

Current hardware used:

• ESP32-WROOM-32E
• USB Cable
• OLED I2C
• Breadboard & 4 wires

When plugged in, the time is initially set to 12:00AM, then the time increments each second.

How to set the time:

• First, if you have not already, download and open the LightBlue app.
• Next, connect to the device's bluetooth access point: "Digital Clock"
• Then, "write" the UTF-8 String value in this format "HHMMSSI"
  • HH stands for hours
  • MM stands for minutes
  • SS stands for seconds
  • I stands for isPM: if AM type 0, else if PM type 1
• Example: To set Digital Clock to time 8:53PM, type "0853001"
