Introduction: 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
Step 1: How to Make This Project ?
Step 2: Equipment List

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.
We have a be nice policy.
Please be positive and constructive.
Nice project, congratulation! I will this build!
How can I download the circuits schematic (PDF, JPG, etc.)?
