LM75 Temperature Sensor with 7 segment display output using PIC16F628

Temperature Sensor

This is a test project built hastily on a solder less breadboard. It uses a LM75 to read the current temperature via I2C and displays the result on three 7 segment displays. It uses a PIC16F628 with an internal 4 Mhz clock.

The program was created using JAL

Note the LM75 is a surface mount device, so I had to solder wires onto it to use it on the solderless breadboard.

Sorry for the bad quality photo. The stuff on the left is a 5V voltage regulator and not shown on the schematic below.
