Love clock
This is an electronic project created on a romantic theme. This project differs from LED hearts that it can be used not only as a gift for Valentine's day, but also used by everyone at work in the office or just at home.
The hand-made electronic device presented to your attention displays the time and temperature sequentially. I wrote a simple MENU with settings for individual user characteristics. Absolutely all parameters are configured in this menu. Such as the frequency of displaying time and temperature, various animation effects are configured.
The effects are divided into 2 groups. The first group is effects that can be displayed every second, the second group is effects that are displayed in the interval from 1 minute to 60 minutes.
The device has a night mode, it can dim the brightness of the display and the heart, or the display and the heart can be completely turned off while it is night so as not to interfere with your sleep. When morning comes, the watch will automatically turn on the display itself. The device operates from a constant voltage of 5 volts.
The device is made on an 8-bit STM8S103F3P6 microcontroller, the display is controlled by the TM1628 chip. The heart consists of 14 red LEDs, they are connected to 74HC595 chips. DS18B20 temperature sensor. DS3231 real-time clock. All chips are connected via SPI and I2C hardware interfaces.
Watch the video of the work in my Instagram: domdevice. I haven't uploaded it to the YouTube video hosting yet.
I would like to express my gratitude to PCBWay for its support. Sincerely, Ivan from domdevice.

Thank you for your feedback! Very pleasant. Yes, you are right, you can add a film as a light filter, this will improve the reading of information during the day, and at night, on the contrary, it will reduce the overall brightness of the display. It's just that this is the first version of the project, these improvements have not yet been made.
