Simple and Fast Internet Clock - Adjusted to Timezone and Daylight Saving Time
This clock is a simple and quick project. It consists of only a few parts. The clock displays the timezone and daylight-saving corrected time. The brightness is controlled by my home automation which sends MQTT messages at sunrise and sunset.
Supplies
- TM1637 display
- ESP-01S
- AMS1117 3.3V voltage regulator
- Capacitors
- Resistors
Hardware and Software
Hardware
See the schematic for the connections. I soldered female header pins for the ESP-01S and TM1637 display on a perf board for easy assembling.
Software
The code for my clock is on my Github. It uses the SevenSegmentTM1637.h and Timezone.h library.
Assembling
The case for the clock is 3D printed. The STL-files are on my Thingiverse page.
The TM1637 display is glued to the front of the case. After connecting the display to the female headers, the back of the case is glued to the front.
The back plate is mounted to my bed.
