The prototype’s outputs consist of a single 7-segment LED display and a piezo speaker (still attached to its watch back). The inputs consist of a 10-position “BCD” rotary switch (for digit entry), two pushbuttons (set and start/stop), and two bits of a 8-position DIP switch (timer selection).[more]

This project is a 3-digit digital thermometer easy to build for beginner or hobbyits.PIC16F628 used to read digital value of temperature from a DS1820 sensor.All 7-segments drived by power logic 8-bit shift register TPIC6B595 with open collector output. For the 7-segment need 12V volt to drive because it have 3 LED per one segment.All segment no need to scan display. Source code programming with CCS C Compiler availible. [more]

This is a test project built hastily on a solderless 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.[more]

In this website you will see several examples how to simulate PIC microcontroller circuit using PROTEUS VSM such as interfacing c,7-segment,switchs etc.[more]

This project uses a standard (PDIP) PIC16F684 as well as a standard thermistor. It will tell the temperature between 0 and 140 farenheit. The temperature is displayed on a 3 digit, 7 segment display. This project is actually quite easy to build; the hardest part is calibrating the thermistor.[via][more]
