7 SEGMENT DIGITAL CLOCK AND THERMOMETER

About: I am a high school teacher of electronics

Intro: 7 SEGMENT DIGITAL CLOCK AND THERMOMETER

It is operated by 12v 500mA adapter.The character height is 57 mm and it shows the hourly information over 24 hours.Time and temperature information are displayed alternately on the same screen.It does not forget the clock information via the memory chip installed on the circuit.There are 3 buttons for mounting on the box.One of these is the MOD button, which is used to change the minutes and hours.The other 2 buttons function to increase and decrease
