Digital Clock

About

This is a simple digital clock that uses a segment display to show time. Connects to Wifi to sync daily.

Environment

• PlatformIO with VSCode
• Using Arduino Environment

Libraries

• WiFiManager
• ElegantOTA

Components

• ESP32 Wroom 32E (ESP32 Development Board CH340C)
• 4 Digit 7-Segment Display 5641AS, 4 x 330 Ohm Resistors
• Push button

Personal Learning Points

• Working with ESP32 microcontroller.
• 4 digit 7 segment display.
• Basic big picture understanding of how Wifi, AP, RTC, and OTA works. But I still depend on libraries.

Connecting to Wifi

When first booting, nothing will display until Wifi is connected. To do so:

1. Go to your Wifi Network list on phone or PC, and find "ClimClock". Wait for a few seconds for it to appear.

2. Select Configure Wifi. Follow instructions given.

3. Wait a few seconds for time to sync.

Subsequent boots will remember the last Wifi configuration, unless it fails to connect.
