Main goal of the project

The main goal of this project is to create a clock based on four gas discharge lamps. The control device is STM32F411E-DISCO.

What has been done so far

To date, we have implemented a clock that can count an hour and a minute. We set up the clock through 3 buttons, 2 of which are responsible for setting the hours and minutes and 1 for switching modes between settings and showing the time. The dynamic display works and the lamps light up alternately, but it seems that everyone is talking. Temperature and humidity measurement is also implemented and shown on the 7-segment display. The body is usually made of wood.

Details we used

IN-1 lamps

TLP627 Toshiba Optocouplers

Decryptor K155ID-1

Real Time Clock DS3231

Temperature and humidity sensor DHT22 and Indicator key-board module TM1638
