Something very special and a real eye-catcher is the soldering kit "binary clock". The board set "binary clock" is ideal for Löteinsteiger and all budding electronics and hobby technicians. More than 40 components are soldered on the board. Et al also an already programmed microprocessor. This makes it possible to output the time "binary" on LEDs. One LED row is responsible for hour / minute and second. The time is set by means of buttons. The enclosed plywood front shows the individual binary values. https://elecena.pl/product/15356616/76334-binary-clock-soldering-kit-for-usb-powerbank-oder-port 2018-12-16 https://elecena.pl/product/15356616/76334-binary-clock-soldering-kit-for-usb-powerbank-oder-port 2021-05-19 https://elecena.pl/product/15356616/76334-binary-clock-soldering-kit-for-usb-powerbank-oder-port 2022-06-14 https://elecena.pl/product/15356616/76334-binary-clock-soldering-kit-for-usb-powerbank-oder-port 2022-10-22
