ANIMATED ADJUSTING CLOCK WITH TERMOMETHER AND HYGROMETER ON 7 SEGMENT LED DISPLAY. I decided to made a clock with few animation when change informations on 4 digit 7-segment led display. a clock who has next informations: - clock, with flash led for beat seconds, about 10 seconds    Brightness can be control in 1024 steps when it used photoresistor or in 2 (minumum or maximum) wirh switch    If is pushed MENU bu*ton, clock enter in adjusting mode, first for hour, so, you will see hour flashing and can be increase value by pushing + bu*ton, but if hour is 23 and + bu*ton is pushed, value for hour is 00..    If is pushed again MENU bu*ton, clock enter in adjusting mode for minutes, so, you will see minutes flashing and can be increase value by pushing + bu*ton, but if minutes are 59 and + bu*ton is pushed, value for minutes are 00.. After that, if push again MENU bu*ton, you can change month (1 to 12) and if push again on MENu bu*ton you can change day of month (just day flash) After a new push of MENU bu*ton, system enter in clock mode (normal mode).     I made a movie for see how clock show the datas and how can be changes clock and data: Note: Schematic work for small led display with common anode    If you want to see in night just clock and temperature, when is day all informations (clock, temperature, relative humidity and data) materials who use recycle pump, I design a simple thermostat to power the pump just if water temperature is bigger than desired temperature. system work like in this photo: - when temperature of heating water is bellow than desired - when temperature of heating water is bigger then desired temperature pump is powered. He use an ATmega8A-PU chip in this schematic (for 14 leds):
