Thermometer with PIC16F84
The project described here is a digital thermometer built with the PIC16F84 microcontroller. The temperature measurement is achieved indirectly, by measuring the time a capacitor discharges through a thermistor. The current temperature, along with a graphical diagram of the temperatures in the past hours, is displayed on a 1×24 LCD panel.
