7 SEGMENT DIGITAL CLOCK AND THERMOMETER

Introduction: 7 SEGMENT DIGITAL CLOCK AND THERMOMETER

About: I am a high school teacher of electronics

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

Step 3: START TO PROJECT

First of all, as you can see in pics, you have to put in all jumpers. And next step...

Step 4: Resistors and IC Sockets

You can see details on pics and PCB layouts and material lay outs. This schematics will help you. Firstly, you use resistors. and than ıc sockets.

Step 5: Displays

And the last step, put Displays. And go...

Step 6: Hex Code

You can find Hex code for clock. Send to your PIC.
