The battery takes 1 hour and 30 minutes to fully charge, and it can run up to 3 days and show accurate time.

What is digiPclock

digiPclock is a digital pocket clock. A pocket watch is a watch that is made to be carried in a pocket, as opposed to a wristwatch, which is strapped to the wrist. So I added a digital screen to this pocket watch, so the face looks like an old analogue clock.

How digiPclock Works

digiPclock has an ESP32, which is the heart of this project. ESP32 has inbuilt RTC so no need to connect external RTC for Correct time information. It shows an analogue clock on the GC9A01 LCD display. The time can be set by the portal. The whole system runs on batteries, so battery saving is also important. I added sleep functionality to reduce battery consumption. Good thing about it is, it does not require internet.

digiPclock is digital pocket clock has 3 features, all three features name are given below.

• Time Setting Mode
• Time Display Mode
• Sleep Mode

Time Setting Mode

In time-setting mode, the time can be configured by a portal (web page). To enter Time Setting Mode, turn the mode switch down and slide the power switch to turn on the device. The instruction to set up time will be displayed in the display.

After entering in time setting mode, turn on wifi in mobile and search for digiPclock wifi. Connect wifi to the digiPclock, as soon as the wifi is connected the mobile will get notification named sign in. Opening the notification will open a web page.

web page has a setup button and a exit button, click on setup button then there will be drop down menu to setup hour and minutes. select hour and minute as your time and click on save, as soon as the setting saved the hotspot from digiPclock will be off and the watch will show time.

Sleep mode

Sleep mode can be enabled by sliding the mode switch; if everything is right, the display will show going to sleep and the screen will turn black. This feature was added to save battery life because, in sleep mode, the ESP draws less current, which can extend the run time of the device.

Time Display Mode

In Time Display Mode, the watch will show an analogue clock on the display; this mode can be turned on by sliding the Mode switch. It wakes the ESP32 from sleep and shows the time on the display. Turn back the slide switch to go into sleep mode.
